Same here.

This is a possibly hacky execution of the following idea: I can move up 
and down the lines and see their buffers displayed, but if I haven't 
pressed RET, I should be able to press `q' and the window configuration 
should return to just the way it was before `xref-find-definitions' was 
called.

But not if the user modifier the window configuration in other ways, 
while *xref* buffer was open, or if the user switches to an existing 
*xref* buffer again after burying it.

Suggestions for a better implementation are welcome. Should we mess 
around with `window-configuration-change-hook'?
