I don't propose to change its default behavior. Just allowing its
customization would be good.

Using display-buffer-in-direction, they don't look the same: after
customization xref-find-definitions can display the xref buffer below,
whereas other xref command can display in the side window.

Emacs has side windows too.

We have Completions for the same purpose.
