It does for me: either click on a completion, or move into that window 
and press C-m on one, it inserts the completion and quits.

But I'm not sure *Completions* is like xref, in the general case: the 
former contains no references; we're pretty sure the user only needs one 
value from it at a time.

Which is usually true for xref-find-definitions, for me. Bot not 
necessarily for xref-find-apropos, or the (newly implemented) 
xref-find-references.
