Hiya,

This version just updates refs as ECH is now RFC9849.

We've no good news as to a 2nd implementation so I guess this
stays parked for now. (Which is ok.)

Cheers,
S.

Abstract:

   We define a well-known URI at which an HTTP origin can inform an
   authoritative DNS server, or other interested parties, about its
   Service Bindings.  Service binding data can include Encrypted
   ClientHello (ECH) configurations, that may change frequently.  This
   allows the HTTP origin, in collaboration with DNS infrastructure
   elements, to publish and rotate its own ECH keys.  Other service
   binding data such as information about TLS supported groups is
   unlikely to change quickly, but the HTTP origin is much more likely
   to have accurate information when changes do occur.  Service data
   published via this mechanism is typically available via an HTTPS or
   SVCB resource record.
