It seems to me it is a good tradeoff for COMI, which is meant to be able to run on constrained devices, to focus on the use of SIDs for identifiers.

OK. This limits COMI applicability to constrained devices in the sense
of a few 100k of memory or devices living on rather limited links.

I am interested in IoT devices that are able to run an embedded Linux
inside. So I am then probably more interested in using RESTCONF with
CBOR encoding since my devices are not that memory limited and I fear
the pain of a global single number managed in a decentralized way will
raise development pain. (So I would love to use CBOR without SID.)
Well, perhaps even RESTCONF with JSON is just good enough (clearly
more attractive for application writers).
