Mandatory subscriptions to a memo-list?

[Michael Schwendt]

Are all packagers/contributors subscribed to fedora-devel-announce?
Is subscription mandatory?

IMO, the recent blow-up of rawhide has shown once more that a way to
send memos to all contributors (in this case "packagers") is needed.
Some commits to packages say "Rebuild for new glibc ABI" which clearly
is based on misunderstanding the wrong broken deps notifications. I this
case, an early memo would have saved packagers from preparing
unneeded rebuilds.

Thoughts?
