I agree, but I will add that it would be very nice if we don't lose the
capability of seeing which command will be run on a file when typing &
(dired-do-async-shell-command) on a file in Dired. It sucks when the
default only says "xdg-open", as you don't know what program that will
open or if it is indeed the one you want.
Does xdg-open have the capability to just print what it would run
without actually executing it? I can't see such a flag on Debian
stable/bookworm. If that is missing, should we perhaps add a feature
request for it?
https://www.freedesktop.org/wiki/Software/xdg-utils/
But in that case, we would need to check for that capability first,
somehow...

Right, we can't just remove it outright.
