I've been looking for information about using TLS 1.3 0-RTT with DoT, but all I
could find was a discussion from over a year ago on the mailing list:
https://mailarchive.ietf.org/arch/msg/dns-privacy/LKZeOAj7Y4fC-9hRcbX_4KVWu0Y

So I wrote this document to try and document potential risks as well as capture
requirements for DoT implementations deciding to add support for 0-RTT (RFC8446
in Appendix E.5 says that "Application protocols MUST NOT use 0-RTT data without
a profile that defines its use).

Most of the wording comes from RFC8470 and some content from the mailing list
discussion mentioned above, though there are still some things that need to be
filled in or expanded.

In this new revision I expanded some of the sections as well as included some
editorial fixes.

The draft is maintained on GitHub at:
https://github.com/ghedo/draft-ghedini-dprive-early-data

Would be interested to know what people think about this.

Cheers
