Thanks for the inputs.

My use case is: when inside a project, the only option to jump to a
certain location is by using 'C-x p g' (which runs 'xref--show-xrefs')
and selecting the desired location from the list of matches in a
separated buffer. I would like to be able to select a single element
from this list of matches, preferably with 'completing-read'.

I took another look in the code, so I guess we can keep the xrefs
functions as it is and tweak 'project-find-regexp' to be more flexible
on this.
