Code review comment for ubuntu-archive-tools:frozen-for-release

FYI, the security team would like something generally queryable so that we also know not to publish security updates during a point release freeze. Our team's current publishing tool uses a lookup in launchpad that looks for milestones in the series to be published that are targeted in the net 7 days, but release team does not seem to use these consistently.

Whatever approach the archive and release teams decide here, please communicate that approach more broadly to the community, so that people outside those specific teams can rely on that as well.

Thanks.
