No particular reason, no.

Indeed. It's a convenient hack, but no more.

Of course if backward-up-list can work all within the string
(in which it currently already DTRT), it should still DTRT.
So it should first try "within the string/comment" and only if
that fails, should it move out.
I'm sure there are more special cases to think of,
