Aww that’s too bad! But at least we still got the other texture modes!
The reason it’s tricky to recreate those brushes is because Krita doesn’t have the “texture per stroke” blending mode which those marker brushes uses. Krita by default does the equivalent of “apply by each plot” in clip studio paint.
You can try to emulate it by using a masked brush tip or lightness map texture mode (appears to have disappeared in 5.0)
