I am indeed "fussy" about "bug reporting".  But here, Dmitry, I am not
reporting a bug.  There's no minimum reproducible recipe, no error
to report, no surprising behaviour, etc. to speak of.  We're just
discussing Emacs development... in the emacs-devel mailing list.
I can't understand what is discourteous about this.

If the user wants marker files to mark the roots of subprojects, we'll
have to access the file system eventually because that's where
that information lives.  It would be a minimal and essential access.  If the
user is discontent with that performance hit (I really doubt it), then
the user may use other means to mark roots of subprojects, like
the one I suggested earlier.

In particular, I don't understand where "traversing a directory tree" comes
in.  That part is completely absent from the solution I am putting forth.
