Please see the latest commits.

In particular, there is now a xref-show-definitions-function.

So in addition to display-buffer-alist, you can change it to give 
xref-find-definitions a particular behavior.

Or to propose a new default behavior, suggest a patch for 
xref--show-defs-buffer. It could do its own things instead of delegating 
to xref--show-xref-buffer, i.e. use a distinct new major mode and 
somewhat different keymap. And also call pop-to-buffer with different 
arguments.

It's hard to comment without seeing, but those windows being to the side 
is, again, probably not my favorite feature. I think Emacs is doing fine 
showing Grep results in regular windows. But please show the patch if 
it's easy, of course.
