[Chair hat on]
There's no mystery as to what it would take to add SHA-3 functions to https://www.iana.org/assignments/cose/cose.xhtml#algorithms. Write a draft that performs the wanted IANA registrations. Targeted drafts with a limited, specific purpose are easy to write. I'll note that my co-chair sent the call for agenda items for IETF 123 out on Tuesday. See "IETF 123 Call for COSE Agenda Items". Respond to it if you want to discuss your draft at IETF 123. Be sure to submit your draft by the Monday, July 7 submission deadline<https://datatracker.ietf.org/meeting/important-dates/#IETF123>.

If somebody actually writes the draft to be adopted here (with the additional Hash/XOF and the MACs), we don't need a separate activity to get the comment about SHA-3 in place - this could just be part of the IANA considerations of this draft. This, of course, assumes that we can do this in finite time; otherwise, having a very short separate draft (which doesn't even have to be published as an RFC) with just the SHA-3 comment could speed up making the registry less confusing. Note that the template for making a new COSE algorithm registration [1] includes providing a value for the Recommended column: Recommended: Does the IETF have a consensus recommendation to use the algorithm? The legal values are 'Yes', 'No', and 'Deprecated'. That is currently "no" for TurboSHAKE/kangarootwelve, if only because these registrations are provided defined by an IRTF document; we *could* upgrade this to "yes".
