We could start by coming up with a list of commands and the use cases
where these commands are useful.  Then we could reason whether these
are important enough to add to the manual.

Do we have in core any feature that provides back-end for the
project.el infrastructure?  It sounds like we only support VC as
back-end in project.el, is that true?
