Multixacts aren't really new, they've been there since 8.1 or so. It's just that their use has been a bit expanded and that their internal format changed a bit. WRT user facing messages: I think it'd suffice to explain the anti-wraparound part of the docs that the same holds true for multixacts. Doing a more detailed explanation seems to require a good amount of low level explanations and thus seems unlikely to be actually read.
