This seems important enough to just send out a patch update that removes the cert and does nothing else. But apparently at least a couple people at Apple disagree; or, something I'm not familiar with makes that type of update impossible.
I mean, I agree with you, I'm just basing my thoughts of what I've seen managers at different companies prioritize as "important" even when engineers cry that a security issue should be of higher priority...
You have to admit that “just a quick patch” isn’t automatically low-risk. You could cause a large blast radius if you rush any patch out without proper testing.
