*Completion* buffers are automatically closed after the selection is
made.  The *xref* buffer is similar in purpose: select a candidate from
a list.  I think it's rarely an advantage but often a annoyance to have
to close the *xref* buffer manually.  We could always have an
alternative key say SPC that jumps to the location without closing the
*xref* buffer.
