@Grum999 and @slightlyangrydodo Continuing out discussion from the other thread - I don’t know for sure, yes MIT is compatible with GPL, but in this context since you use Krita API your code needs to be in same license to not violate krita’s license I think. Also if the plugin code is MIT someone else might that code and include in proprietary stuff since it is MIT and it is okay. But then that would also violate krita’s GPL license and create confusion.
