Well...  they are dired-specific, because they're only used in dired.
(And using them elsewhere would be pretty surprising.)

Emacs does have a problem in this area, though -- I'm guessing there's a
dozen different packages that define similar functionality (i.e.,
"what's in mailcap but with some extras"), and consolidating these would
be nice.  But the problem is that there's different use cases -- the
things a person wants to do in Dired isn't necessarily what they'd want
to do in Gnus when receiving an attachment).

And so we're where we are.

So I don't want to make the minibuffer function depend on Dired, and I
don't want to make these things non-Dired-applicable (because that'd
annoy people who have customised their Dired experience), so there's
nothing actionable left here, and I'm closing this bug report.
