I think there's a misunderstanding, but it's ok.

Richard, the main `new feature' of a DVCS is not that it changes
anything about the `central' repository.  It would still be possible to
name a well defined, well known place where the official Emacs source
tree lives.  Since savannah is a well known place for Emacs, that's
where the official tree should be, of course.

... and this scratches the surface of the `new feature' of a DVCS.
There is still a `central' repository, which is well known and used for
the official releases.  But developers can *also* collaborate with each
other by directly exchanging changesets with each other.  They don't
have to specificlly go through a single CVS tree to do this.  They still
*can* go through the `central' repository for all their work, it's just
not mandatory.
