My OP (in the other thread) was about underlines. With my proposal, the behavior would not change on Linux for straight underlines.

How would a library depend on this, given that it isn't consistent across platforms, and not observable from ELisp?

Sure. But until someone voices support for what others consider as a bug, it might not make sense to expend resources adding a flag to revert to the old behavior. 
In any case, maybe we should move this discussion to #26958?
