I recall Spencer mentioned that 'C-x p f M-n' is the quickest way getting
a file name relative to the project root for using it for external references.
And I use the same case very often too.  (I mean the case of
'(project--find-default-from buffer-file-name pr)').

OTOH, thing-at-point is too specific to a programming language,
and can be used to navigate source code by placing point on
an "include" directive with relative a file name, then
'C-x p f M-n M-n' will help to find the referenced file.
This is a poor man's way for source code navigation, since 'M-.'
doesn't support navigation by project relative file names.
