New features of Krita 3 Greater Blending Mode is amazing.
Because there is no overlap in touch, it maintains consistent alpha values and reduces the number of blender brushes used. Very elegant painting method.
TVPaint Animation works basically the same painting method too, but unlike Krita, it is one-shot.
Krita is persistent and very clever because it classified this painting method as a blending mode.
But there is one thing that is not good.
This blending mode doesn't work in Erase mode.
You can check the attached GIF of top to see the touch overlaping in Erase mode.

As a result, I want the Greater blending mode to work this way in Erase mode, as this GIF shows.
But in fact, this case is over-painted white color for example to help understanding what i want.
So alpha vlaue is increased and it make problems when working with BG layer.

Is there any correct way to do this I don't know?
Or is there room for improvement in the next release?

This sounds like something that could be really helpful, like a "Greater-erase" blending mode, or something like that. I hope this gets more attention, see if other people would like the feature as well.
