The number ten might be a little excessive. But there is talk of
multiple sessions being simultaneously for resumption, and multiple PSK
identities in the original meaning of that term.

So I suppose there are certainly use cases where a "HRR and let the
client *guess* what we might like instead" model would lead to more
round-trips than an explicit indication from the server.
