Not well, no. There are discontinuities, and if I use wide characters (like CJK spaces, e.g. ' '), portions of the line are misaligned.

No, I don't think they are the majority of Emacs :)

Alternatively, would it be hard to add a vertical strike-through face property? (I've used horizontal strike-through as a way to display horizontal lines in the past)

Maybe? At the moment boxes and backgrounds already span the full line height, so I'm assuming strike-throughs would as well.
All that I was pointing out is that the box display code already draws lines that reliably span the entire line height.
