Nor can you say that there is *not* enough interoperable use. As others have 
pointed out, there are lots implementations, and as far as I have heard, all 
current implementations are using RFC 5930.

That's fine if you want to recommend it; many implementors are ignoring you and 
interoperating just fine.

That may all be true, but it is also irrelevant to whether the RFC itself 
should advance. The IANA values are not in question: only the bits on the wire 
are covered in the RFCs. The bits on the wire in RFC 5930 are highly 
interoperable, as shown by many different implementations (possibly even yours).

Do others in the WG feel that the issues Tero brought up are significant enough 
to prevent RFC 5930 from advancing on the standards track?
