It's a good starting point, but the copyright assignment issue is not
the only issue (not even the main one, from my POV).  The main issue
with NonGNU ELPA, IMO, is that packages there don't necessarily adhere
to the Emacs coding conventions, are not supervised by the Emacs
maintainers, and do not have to coordinate their development decisions
with the Emacs team.  So their integration into Emacs could be less
seamless than that of packages from GNU ELPA.
