Do you have any details on which client software and versions you've
tested, Mathias? I've been looking at doing this but I've been more
concerned about the client experience than s2s issues.

You say "very few" users had issues - what was your sample size? It's
really hard to get in touch with a user if you stop their connection
from working, so I'd be really hesitant to jump into something like
this without a lot of warning and publishing required minimum version
information somewhere for them.
