I think it would be desirable to change the default UI just enough so
that a code like Xref can make `completing-read` display the
completions eagerly.

One thing we can already do is to make Xref use a completion category
with an entry in `completion-category-defaults` which specifies a value
of t for `completion-cycle-threshold`.  This way a simple TAB should
select the first entry.
