That's what I wanted to discuss, if I had a concrete suggestion I would
have submitted a patch.

All in all, I think that xdg-open and similar commands are more
practical than for example xpdf, xloadimage, etc. Systems with xpdf,
xloadimage, etc. but without xdg-open are probably an extreme minority,
but nobody can say for sure -- and changes shouldn't come at their

I was thinking about improving the guessing system to support multiple
programs and check their existence. Assuming the structure of
dired-guess-shell-alist-default may be changed, it would seem like a
good compromise.
