Hello WG!

I'd encourage the WG to review this document - it's relatively short, and
is an easy read.

ECH is likely to be a fairly active topic in the IETF, and has significant
Opsec implications. The document is on the OpSec agenda, and so having read
it before the meeting will be really helpful..
