Re: [Rats] Where does a EAT end? (was: Re: WGLC for https://datatracker.ietf.org/doc/html/draft-ietf-rats-eat)

Hi Thomas,
hi all,

I'd also like to add that I am bit puzzled by the fact that there is not 
a single area review commissioned for this I-D that is perceived as a 
"central item of the WG" (as far as I understand it).

I think there would be tremendous benefits stemming from reviews by the 
art & ops area, as well as the secdir and the iotdir, before we move to 
something that would resemble a WG consensus.

I am aware that we can do that also post first WGLC. I am just perplexed 
that we did not do this beforehand. Why is that the case?

Viele Grüße,

Henk
