ECS was already implemented by various operators. The _informational_ draft (it is still in IESG eval) is just documenting the existing implementations. AFAIK, there is going to be a new standards track draft once the various implementers resolve differences in behaviour. In light of the above it will be interesting to see how a standards track draft gets on. Also section 7.1.2 does say:
“A SOURCE PREFIX-LENGTH of 0 means the Recursive Resolver MUST NOT add
address information of the client to its queries. The subsequent
Recursive Resolver query to the Authoritative Nameserver will then
either not include an ECS option or MAY optionally include its own
address information, which is what the Authoritative Nameserver will
almost certainly use to generate any Tailored Response in lieu of an
