I think maybe just to limit the signal to noise ratio.  Maybe I'm
specifically interested in macro expansions only.  But I kind of agree
that, at least  in Lisp, calling and expanding isn't usually very different
in terms of what I want to know about such a site.

Anyway, does this mean that xref.el is soon to have a solution for
this?  The one I vaguely remember discussing in this thread.  Something
like a single xref-find-other command + a selector for the type of
reference, right?
