> I don't want to force retirement to be in multiple phases in edge cases like this, but I think it's fine to limit RCID to max_connection_id_limit outstanding frames. Later, when some RCID frames get acknowledged, check if there are more CIDs that need retiring. The case when the limit is exceeded needs to be handled in some way, so I'd rather have that code hit very infrequently than basically never.

I think I agree that tracking 2*max_connection_id_limit of RCID frames in just one way taking care of these edge cases. I'm fine with leaving it up to the implementations how they would deal with this problem.
