From a technical point of view, I believe we can merge this feature
with existing airbrush, paintbrush, eraser and other brush-core based
tools.
And users want this feature both for paint brush and eraser. So adding
extra toggled-dynamic-mask-options for paint brushes is a good way.

Only drawback of that approach is that users should set up appropriate
parameters both for paint brush and bucket-fill algorithm.
(e.g. this feature should be used without dynamic opacity etc.)
We can solve that by providing tool presets, though.
