   Please look at 'CONTRIBUTE' in the repository, which is
   intended to be the official "Welcome, New Emacs Developers"
   write-up.  If what you think should be there isn't, please
   don't hesitate to propose patches.

That file is oriented to Emacs per se.  What is needed in
addition is some formalization of the relationship(s) between:

 - GNU Emacs, the source repo
 - GNU Emacs, the releases
 - ELPA
 - other emacsen

especially wrt lifetime and compatibility expectations.  IMHO,
this kind of inter-project policy-ish documentation should live
on Emacswiki.  Who will step up to write a first draft?
