Let me just say 'hear, hear' to that, as one of those typical 
package maintainers. I thought about using ELPA instead of MELPA a 
few times, but reading such comments as "arcane git commands", 
"mashing up your history" and "breaking the entire ELPA repo", my 
immediate reaction is "oh well, some other time, perhaps". 

I should probably point out that my git skill level is low, and 
while I'd be willing to learn more, the time investment if often 
prohibitive. (I'm not a professional programmer, just a guy with a 
hobby.) With MELPA, that's sufficient, though, and Github has a 
lot of help pages that provide clear and concise instructions for 
things I don't do every day, such as dealing with PRs or keeping a 
fork up-to-date with its upstream repo.

I've just been skimming the GNU ELPA README on 
http://git.savannah.gnu.org/cgit/emacs/elpa.git/plain/README and 
although it *looks* like once thing's are set up, I shouldn't have 
to do much more than a git push to update my package, the process 
of getting there seems quite involved.

More importantly perhaps, the entire workflow seems to be 
different. With MELPA, I put my code in a publicly accessible repo 
that I create myself, on a service of my own choosing (in my case 
Github), and then tell MELPA where to look for it. With GNU ELPA, 
it seems I need to put my code somewhere specific, and it's not in 
a repo that I create or own.

In itself, it's not a big problem that GNU ELPA uses a different 
workflow from MELPA, but, speaking for myself, it would be good if 
the ELPA README (or some other document) would contain a few 
paragraphs explaining the differences and would cover the steps 
involved in such a way that they make sense for someone with a 
less-than-stellar understanding of git.

Anyway, just my two €0.02.
