"A well-formed RFC starts with a well-formed Internet-Draft."

For example, here is the Internet Draft for IPv6 which eventually became RFC 2460
https://www.ietf.org/archive/id/draft-ietf-ipngwg-ipv6-spec-...
Why not discuss the I-D itself. Many drafts are garbage but simply being a draft does not by itself tell us about its likelihood of becoming an RFC or standard
