Right, that idea eats dust.

What about users who change the region or hl-line faces to use
underlining?

IOW, the problem with the attribute-level idea is that it will affect
those attributes regardless of the face from which they came.

So I now tend to think that if we consider some faces not eligible for
extension, we should not extend any face attributes at all.  Too bad
no one else except the 3 of us is talking in this thread; we need more
opinions.
