Rather than get bogged down in the minutiae of the requirement and the nature of confirmation, let's just say that this was added when we added the definition of "confirmed".

But an endpoint that can accept 1-RTT in key phase 0 can also receive 1-RTT in key phase 1 equally well.  So there is no functional reason not to allow updates as soon as 1-RTT keys are available.  I think that we should just loosen this entirely.  It might not be a good idea to waste a key phase like that, but it certainly doesn't break anything.
