Hi, I just submitted -03 draft-mattsson-cose-cbor-cert-compress-03.
The changes has already been sent out earlier. Two new changes are: - "L = ceil( log2(n) / 8 ), where n is the size of the largest prime-order subgroup" Thanks for a quick answer Rene! - Added CBOR encoding of DER certificates that already use point compression. My understanding is that is not commonly used, but maybe it will be in the future.

Name: draft-mattsson-cose-cbor-cert-compress Revision: 03 Title: CBOR Encoding of X.509 Certificates (CBOR Certificates) Document date: 2020-11-15 Group: Individual Submission Pages: 27 URL: https://www.ietf.org/archive/id/draft-mattsson-cose-cbor-cert-compress-03.txt Status: https://datatracker.ietf.org/doc/draft-mattsson-cose-cbor-cert-compress/ Htmlized: https://datatracker.ietf.org/doc/html/draft-mattsson-cose-cbor-cert-compress Htmlized: https://tools.ietf.org/html/draft-mattsson-cose-cbor-cert-compress-03 Diff: https://www.ietf.org/rfcdiff?url2=draft-mattsson-cose-cbor-cert-compress-03 Abstract: This document specifies a CBOR encoding of PKIX profiled X.509 Certificates. The resulting certificates are called "CBOR certificates". The CBOR encoding supports a large subset of RFC 5280, while at the same time producing very small sizes for certificates compatible with RFC 7925. The CBOR encoding can be used to compress DER encoded X.509 certificated to encode natively signed certificated. When uses to compress DER encoded X.509 certificates, the CBOR encoding can in many cases compress RFC 7925 profiled certificates with over 50%. The document also specifies COSE headers for CBOR certificates as well as a TLS certificate type for CBOR certificates. Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
