As a chair, I'd like clarity on what you mean by "the single algorithm design".
Do you mean that each algorithm identifier fully specifies all the
cryptographic parameters being used? Or do you mean that a single algorithm
identifier is used for all the HPKE possibilities?
Speaking as an individual contributor, I fully support the first (fully
specified) choice. Whereas the second possibility will cause endless
interoperability problems.

Subject: AW: Draft IETF 117 COSE agenda
Hi Mike,
the content issue with HPKE is the single algorithm design. I have posted a
summary about it to the list, see [COSE] COSE-HPKE and the Single Algorithm
Discussion
(ietf.org)<https://mailarchive.ietf.org/arch/msg/cose/_GQXXpltAgXNozXIFC9z1yY1CCM/>
It needs a consensus call from the chairs to finalize it.
You could start this call today and be done with it by the time of the meeting.
Ciao
Hannes
