The registrations in question are in section 8.5 -  8.7 of draft-ietf-lake-edhoc-09: The extension of 'kid' to int (both as a reference and in the referenced object) and the registration of 'cwt' to signify that the value is a CWT or UCCS.

A few reasons have been mentioned for moving this from EDHOC to a COSE draft, I don't know what is most relevant, if anything:

* In case of 'kid', these registrations would make EDHOC an update of draft-ietf-cose-rfc8152bis-struct (RFC-to-be 9052). I don't know if LAKE or COSE wants that. 

* These registrations are independent of the base EDHOC protocol, but enables the use of CWT and UCCS as credentials, and more compact identification of credentials. Therefore they could instead be referenced from EDHOC. I don't see why the reference needs to be normative.

* These registrations belong to the COSE domain and may gain better awareness and reviews if put into a COSE draft.
