Yes, this is what felt artificial to me.  Why would I want to restrict
myself to a file dialog which offers only part of the functionality of
another one while giving me no advantages?

In this case we'd probably need a simple replacement.  Or we drop tool
bar support for Emacs 21 as well which I would not like to do at the
current stage.

I just checked, it's only a missing button.

Problem is that Emacs 21 and Emacs 22 use the "open" icon for different
things.  Emacs 21 for "Open directory" and Emacs 22 for "Open existing
file".  So applying the change will likely lead to confusion for Emacs
21 users.  How about defining parts of
`toolbarx-default-toolbar-meaning-alist' differently depending on the
Emacs version?
