I'd rather have only one of the two (either `:maintainer` or
`:maintainers`) but not both at the same time.  The downside for those
few multi-maintainer packages is fairly small (its only impact is that
`describe-package` will not show the maintainers, which is what we've
had for many years).

Nothing specific on ERC's side, no.
But patches for `elpa-admin.el` and for Emacs would be welcome (tho
extra time would be welcome as well :-)
