The draft reserves 2 names, which is fine. The question is who is going to be authorized to change these reservations into proper registrations.

The difference between IESG Approval and Expert Review is who is going to decide to mark an IANA registration entry as properly registered. IESG is a collection of 15 people, whose membership partially changes every year. Current IESG knows almost nothing about EBML. An appointed Expert would have more context to make a decision. So I think it makes sense for an Expert to handle this, instead of overloading IESG.
(Maybe the following analogy would help: asking IESG is like asking a Board of Directors to make a technical direction. While IESG is ultimately responsible for the decision, it would prefer to delegate the decision to technical experts.)

Does this make sense?

Best Regards,
Alexey
