Steffen and I discussed this with Jim last year in Prague, if I remember correctly, and he recommended to submit cmp-over-coap to ACE and not to LAMPS.
As est-over-coaps was in scope of ACE, I also think it is quite obvious to discuss cmp-over-coap in ACE.
Looking into Mohits draft, cmp-over-coap is much simpler than est-over-coaps, as CMP does not need any binding to an underlying (D)TLS handshake.
If you think this needs rechartering, we should go for it.
