All of this is true for the "advanced" method as well.

The only advantage of `make depend' is that you can run it after you have
already built.  But then you have to remember to re-run it all the time,
otherwise the point of having accurate dependencies is gone.  So this
might be useful for someone installing a patch into a header file and not
wanting to rebuild from scratch, but that's about it.

What we could do is ship the dependencies (.deps/*.P) in the tarball.  
That would require running an entire build before making a tarball, but it
would be a nice service to users.
