One frustrating aspect of this debate is how many are neatly categorizing artists into ranks of good and bad – talented and not talented, skilled and not skilled – to then use that hierarchy to dismiss arguments instead of considering them on their merits.
The value of your words doesn’t rest on your ability of wowig people with your work. A beginner’s word isn’t worthless because they didn’t reach the point they want yet. Talent? As in innate talent? It’s an illusion! It’s so rare you might have never ever met any artist like this. 99.999% of the artists you look up to sit on a mountain of bad drawings that’ll never see the light of the day.
You’re not your work. You aren’t a failure for struggling, morally inferior, or devoid of value as an artist and as a person. You don’t sit above other people either when your work stuns people, you’re not more valuable, with greater rights and entitled to be listened to and to command the masses of “lesser” artists. Disagreeing with you isn’t a defect of character.
The only thing that someone’s “bad” work tells about them is that they didn’t have enough time and opportunity to reach their goals. It doesn’t even tell us if they’re beginners though we often use it as a gentle shorthand for it. It may be that they simply didn’t find a way yet to study and practice art that accomodates their physical limitations and speaks to their minds. We’re all on a learning curve.
What being skilled tells us is that the person is likely a long time at it. For being a long time at it they have insight into the process, and perhaps into the industry when they also practice art as a profession. Only this. It doesn’t give authority over the subject or worse, how other people should work. The idea of decreeing how other artists should work is absurd. What the hell, people?
The same is valid for being a professional or hobbyist. The point of weighing the words of a pro is not that they have clout because people throw money at them for their skill, it’s because it affects their livelihoods and to try to exert control over how they work is not only to try to control how their art is made and looks, it’s to deeply impact their ability to survive.
So should disabled artists points be listened to with extra care for similar reasons. It should go without a saying that what isn’t a problem for you is an obstacle to others created by no personal failure of theirs.
So, can we please not weigh arguments on the “betters” and the “lessers”, the ones doing rightart and wrongart, and consider instead who will be affected how by this proposal?
Another point is potential bullying caused by this feature.
Yes, it’s worrying. I don’t mean to minimize or brush aside this concern when I say it though: Someone set on hating you will hate you no matter how hard you contort yourself into knots to shield yourself. They’ll hate you your work your cat and the way you eat crackers.
Nothing you can ever do will be enough to change their mind. This isn’t an issue Krita can cause or solve, this is a societal issue.
They’ll accuse you of being a “lesser” artist and point out at Krita having “ai” features as a proof, and when they lack anything to misrepresent as proof they’ll simply make it up. Thing is, does this hatred have any concrete consequences to your life?
Having large groups of people sicced on you certainly has, having your professional reputation has, but thankfully most bullies are just john2903781 from the internet. Chuckle a little at the absurdity of them proclaiming they know who you are from half a dozen words and a 12am sketch, then block and they’ll forever disappear from your life. You don’t owe them your time, energy or attention they clearly crave. You don’t owe them any proof. Boy, they wish. 
Don’t take it as “grow a thicker skin”, that’s horrible backhanded advice – as if resilience grew on trees and lacking it was (again) a character defect! Take it as a reminder that if you step back a little you can find ways to protect yourself that don’t involve constantly worrying about not providing ammunition to people out to hurt you, because that anxiety alone, that stone around your neck, it will consume you.
And in the worst case scenario, if you’re set on having a so called clean copy of Krita as proof that you don’t rely on any aid for your linework – then you can always fork the project and share the fork so it’s verifiable by any finger pointers.
