I'm not sure it really helps unless there is no limit because in some
cases a single SRPM will produce more than 20 distinct packages and then
you won't even get the full update history if you're polling constantly.
 CentOS often releases several updates at once, and it's not uncommon to
see 50+ distinct RPMs released within a few hours.

I don't understand the goal of this replacing the mailing list posts
with this.  It means we no longer have any persistent notification or
metadata for updates unless we watch the actual repos or build systems
directly.  This feels like a huge regression from what we have been
getting for CentOS 7 and older.

If you provided a persistent updateinfo.xml in the repos instead of
sending the emails that would at least be equivalent coverage (and
community members have been asking for this for ~10 years), but this
strange RSS thing isn't getting us close to either that or what we had
