Could you explain why thiis way is better than changing to TLS 1.3?
It is often the case that organizations will find it easy to make a fairly minor change rather than installing a whole new version. You’ve never seen this?


The draft isn't a minor change: it makes handshake and record layer changes so everyone would need to install new software and suffer similar compat issues as with a 1.3 update.

yes, mandating use of EMS, GCM, and rfc7919 is a small change,
changing wire format of messages is not
(I bet that there are middle boxes that will choke on the new ServerKeyExchange)
