15.8.2 isn't released, but the 15.8.2 release candidate clearly is. I don't think think it's that crazy for people to be at least somewhat concerned that a fairly common important library got broken a bugfix release to a maintenance update that came out a month ago for a major version that came out two years ago without anyone internal testing it before publishing the RC.
They used to make these beta versions private so only ios/macos developers could test on them to report bugs to get them fixed before public release. They since opened it up to anyone who wants to install it which generates a lot of outrage from the peanut gallery when the beta has bugs.
I think the reason so many people hit this in particular is enabling Sequoia beta channel is the only way to prevent the machine from wanting to upgrade to a newer major release.
