That's possible to implement.

But the single/multiple overlay decision is just an implementation detail
Currently Flymake uses one "end of line" overlay only, but here the logic
o control that uniqueness failed, so an extra unintended overlay was
created, and that created problems with cursor placement.

But your suggestion is noted, though.
