I wasn't aware of CBOR as I have yet to come across a project that needed an alternative to MessagePack or even MassagePack (only considered using it once in the past). However, based on my experience on various projects, if you have to get approvals and buy-ins from architects, legal, and security teams, using something that has an RFC helps you win those battles regardless of the technical merits of a RFC or non-RFC backed project/tool/protocol.
