That's a lot cleaner.  Thanks.  Some minor quibbles, but I like this

A question about client certificates prior to TLS 1.3: Are we happy
making compression for client certificates only available in TLS 1.3
(or higher if we can assume that we will maintain parity in future)?
I think that I can live with that.
