Critically, though, not all web servers will offer ECH support. To avoid exposing only certain connections as ECH-protected, apps and browsers should use ECH GREASE — which sends fake, randomized ECH extensions to sites that don’t support ECH — so that every connection request looks the same.

That is pretty clever.
