I opened a PR to address this in the document -
https://github.com/tlswg/draft-deprecate-obsolete-kex/pull/12
This updates the IANA considerations section to say:
"This document requests IANA to mark the cipher suites listed in
{{appendix-dh}}, {{appendix-ecdh}}, {{appendix-dhe}} and in
{{appendix-rsa}} as "D" in the "Recommended" column, see
{{I-D.ietf-tls-rfc8447bis}}, in the "TLS Cipher Suites" registry."
