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

I am definitely not a fan of unconstrained fan out here. Probably the right thing to do is require any additional token type be an IETF standard.

One reason I made these sockets is so that UCCS/UJCS will plug in and be part of a submod Nested-Token and part of a DEB. It is important that UCCS and UJCS be brought into EAT this way.

Personally, I think it would probably be good if this never went beyond UJCS/UCCS. 

I’m still digesting Simon’s collection proposal…

Thanks for point that out, Thomas.
