I guess there's no need, so OK, no signing of `archive-contents'.

OK.

I thought the maintainers would have their own keys, and they would sign
a GNU ELPA "signing subkey" that's only used for releasing.

Debian has good docs on this:
http://www.debian-administration.org/article/450/Generating_a_revocation_certificate_with_gpg
http://www.debian-administration.org/article/451/Submitting_your_GPG_key_to_a_keyserver
http://www.debian-administration.org/article/452/Using_gnupg-agent_to_securely_retain_keys
...and the GPG handbook talks about these topics as well:
http://www.gnupg.org/gph/en/manual.html#AEN385
http://www.gnupg.org/gph/en/manual.html#AEN464
http://www.gnupg.org/gph/en/manual.html#AEN526
Take a look. I think a signing subkey will work, but will let you
judge. If you think this is workable, I'll start on the code and put
together a POC.
