I would seriously consider just removing one of the modes. Having two
modes is complex enough, and then having different defaults in different
versions, and fuzzy recommendations like, it's better for "smaller
systems", it's quite confusing.
I don't think it's a fundamental problem to say, you need 2 connections
to use this feature. (For example, you need a second connection to
issue a cancel request. Nobody has ever complained about that.)
