Now it sounds like we agree. There are some commands that I don't find useful
(for my own needs) - I'd add `dired-info' and `dired-rmail' to those you
mentioned, for instance. Dunno whether someone else might find such commands

Rather than having a predefined command (e.g. `dired-info', `dired-rmail') - let
alone a key, that just calls an Emacs function (e.g. `info' or `rmail') on the
current file (or the marked files), it might be good to have a key/command that
reads an Emacs function (even a lambda form) to apply to the file(s) - a la `!'
but for an Emacs function instead of a shell command.

The dired/dired-x split was long ago. Looking at the Commentary, it seems it was
not a split but just a decision not to merge dired-x into dired. Back then,
things like load time and memory might also have played a non-negligible role in
such decisions. (Meme combat for dired-aux.el.)
