I know, right? It's like some people feel the need to say (for me, I'm not seeing problems). That's an anecdotal sample of 1. With any issue, even if it's widespread, there's going to be some people who don't have it. That's a given. So hearing about a one-off case of someone who has no issues offers nothing to the conversation.
This one is tricky. One site said it's only a problem if you first install Safari 14 and then 2020-005; but not if you don't have both, and not if you install them in the opposite order. So some people will have either or both and be perfectly fine, and some won't.
edit: there are of course problems that affect everyone (although perhaps not everyone notices). But those are likelier to get caught in testing than one that doesn't affect everyone. Coming up with tests to cover different non-whole-system update combinations (which should usually be ok, but sometimes won't be) is crazy, because the number of combinations goes up very fast relative to the number of separately installable updates. But smaller updates are faster, and people like that. Solaris 11 has a good (IMO) approach: a package management system that ensures all update sets are consistent, and as needed (or optionally if requested even for minor updates where it wouldn't do it automatically) takes snapshots so one can roll back updates with one command and a reboot.
