Fair enough, I guess.  But I still have the question
of whether we can do better here.

Also, I think `C-x b foo' followed by `M-x org-mode'
behaves the same, though no file buffer is involved.

A mode hook doesn't have any necessary relation to any
file or to `auto-mode-alist'.  It may be that Emacs
has chosen to relate the two in this way, as a kind of
shortcut, but there's no necessary connection, right?
