Okay then, though I'd call them just "bundled" packages from that point. 
Since "core" is an ELPA term for packages developed inside emacs.git.

That separation could also be considered a win, saving time for some of 
the developers. Which could make up for the extra overhead with managing 
stable tags.

Note that to do the above, we don't really have to implement this stuff 
as a feature in Emacs (as a UI in package.el), or in elpa-admin. At 
least not right away.

As long as we've agreed on a principle to choose releases to tag as 
stable, we could just write those git revision down somewhere (using git 
tags, or some text file in the Emacs repo, or a text file on a server 
somewhere, ...). And then use that info when bundling the packages.
