A couple corrections…
(Sorry for the overly wide reply.)

> See appended, CarstenB complained

I didn’t complain — I just informed you of information that I wasn’t sure you had (apparently it indeed hadn’t reached you in any other way).

(Well, I had the list set up before there was a CBOR WG and I still get the bounces…)

Yes.  This is probably related to the IETF mail server being moved to a new address recently, which may have previous dirt attached to its white shirt.

> If i read correctly what they write,

Well, they’ll try to tout the quality of their data, but we do know that this is a hard problem…
