Hopefully-final draft-ietf-dnsop-svcb-https-04 and nearing WGLC

We've closed out most of the open issues on draft-ietf-dnsop-svcb-https
and it will be going to WGLC shortly.

Current version at:

      https://www.ietf.org/archive/id/draft-ietf-dnsop-svcb-https-04.txt

Hopefully we're done, but you can open issues against:

    https://github.com/MikeBishop/dns-alt-svc

This will likely get batched up while waiting for TLS ECH to publish due
to some cross-dependencies.

Abstract:
   This document specifies the "SVCB" and "HTTPS" DNS resource record
   (RR) types to facilitate the lookup of information needed to make
   connections to network services, such as for HTTPS origins.  SVCB
   records allow a service to be provided from multiple alternative
   endpoints, each with associated parameters (such as transport
   protocol configuration and keys for encrypting the TLS ClientHello).
   They also enable aliasing of apex domains, which is not possible with
   CNAME.  The HTTPS RR is a variation of SVCB for HTTPS and HTTP
   origins.  By providing more information to the client before it
   attempts to establish a connection, these records offer potential
   benefits to both performance and privacy.
