Way to ignore certain requirements test

I'd like to see some way of ignoring certain requirements results, without having to turn off requirements checking entirely. E.g. right now I've got a site where I'm running the core Aggregator module, which is deprecated. This means that that site always shows up in at least a warning state, because requirements reports a warning on a deprecated module being used (and while it's supposed to have been moved to contrib, the contrib version isn't ready for prime time yet). Day to day, I'm not really interested in that. Turning off requirements checking, however, also turns off module updates being available, which I am interested in, day to day. It's one of the reasons I have my site being monitored by Nagios in the first place. So a way of being able to say "on this site, don't consider this part of requirements checking in reporting back to Nagios" would be handy. Similarly, I've got sites still on 8.9 that of course, report an unsupported Drupal release in the status page and to Nagios. Being able to turn that off for reporting to Nagios would make monitoring that site (until it is updated) for other day to day problems easier, as it wouldn't be constantly in a critical state just from the old version of Drupal.

Note that for the first scenario, ignoring the Aggregator module does not cause the Deprecated Module Used warning to turn off. So the current module ignoring facilities does not produce the results I'm looking for.
