Whether nice or not, that's irrelevant to this bug
report, IMO.  Sure, it talks about using another
window - that's all.

Opinion about `other-frame-window'?  Not related.

Was the case of a dedicated window for the *xref*
buffer tested?  That's a case I reported about.

You mentioned *grep* as being the _same_ as *xref*.
I wish *xref* _did_ behave like *grep.  The problem
is that it doesn't.

As I said in my report, I use dedicated windows for
buffers whose names start and end with `*'.  E.g.,

 (setq special-display-regexps '("[ ]?[*][^*]+[*]"))

*xref* should be the same case as *grep*, but it's
not.  The bug was reported for *xref*.

With grep, `RET' or `mouse-2' on a search hit invokes
`compile-goto-error', which does `next-error-internal',
which DTRT - it opens the search-hit buffer in a
window other than that of the Dired buffer.

That's the point of the bug report - a request to make
*xref* behave properly, like *grep* does, when choosing
a search hit.

If this was fixed, great; thanks.  If not, then I guess
this is just another "won't fix".
