Either a new NIP or a section within NIP-34 so the protocol is clear and it is easy for clients to implement if they wish.

I see the 'release artifact set' in the 'Examples' section of NIP-51 but there is more to the protocol than that.

There are three aspects: 1) application profile event, 2) release event 3) trust attestations

I started to draft something and that process brought up some questions and scenarios it might be worth discussing.
