Not really: the GNU ELPA packages are generated from code kept in the
`elpa.git` repository, but it can also use the code in Emacs itself
(i.e. in the `master` branch of the `emacs.git` repository), which is
what happens for ERC, Python, and a few more, whose "upstream" is
Emacs's own repository.

It's not limited to single-file packages.
The ERC package is one of those.
