No need to poll about that, I think.

As long as we change the default to one of the current two alternatives, 
TAB won't play any role in either (the -at-bottom function sets up RET 
to call the same command).

Then we can safely remove/change the TAB binding in 
xref--xref-buffer-mode, or alternatively, create a new major mode that 
is slightly more Grep-like, and use it in the default 
xref-show-xrefs-function.
