If I may go out on possibly a very long limb here, and answering
your specific question my understanding of project.el is that it helps in
writing a "project implementation backend". It is that backend that
understands Makefiles and supplies these bits of information, via
project.el's API to interested Lisp programs, like xref, perhaps
"M-x compile" or some other project-wide command.

I'd welcome that, provided it becomes popular enough that some useful
backends actually do get written.

But I may be misreading the whole discussion, it's indeed become a
bit confusing.
