The latter approach requires more user code.
I'd say it's a bit like the difference between having a
post-self-insert-hook and not having it, asking users to rely on
post-command-hook.

I don't know these uses, so can't really comment, I guess.

Sure. I think we've collected the requirements by now, though. Time for
an implementation?

IMHO the question of removing the irregularity introduced by the native
line numbers using the new shared margins support is a fairly important
one. But it's not urgent, of course.
