I've just described in the other thread that I would like to have
finding references and finding files to be able to operate on either
sub-projects or super-projects on demand.  This is the problem I'm
facing, and it's not new.  For example, there is only: find file in the
very large project, and find file in the current directory.  There is no
"find file in this section of the repo, which is a sub-project in
itself".

IMO, it's not "improper" to describe problems and use cases: in fact I
prefer that people describe over jumping to vapourware solutions.  But
if you're really looking for a suggestion as to _how_ to design it, I
suppose my problem would be well dealt with a negative prefix on C-x p g
and C-x p f giving me a choice of which project to operate on.  But that
is only one possibility: new commands are also acceptable.

As to how one defines sub-projects, I think having
project-find-functions be used to compose a list of projects (as opposed
to to stopping after finding one) would be a nice way.  It would be nice
if the elements of project-find-functions could be informed of the
projects found so far.  But keeping the "stop after first" behaviour and
having members return a more complex object is maybe also good.  I
really don't care much what you eventually choose, as long as I can
solve my problem.

The current Eglot solution to start servers in sub-directories of
repositories has already been described (and apparently accepted).
