Requiring an Oauth token is heavier lifting as Oauth requires Https as the foundation. (And yes I accept that some calls may not require any authz at all, and be publicly accessible)

This is a great example for why any early binding at this stage is likely a poor choice.

IMO, what we should be doing is defining an extension mechanism that allows any number of auth mechanisms to work interchangeably, like we did with crypto-suites for the DID and VC specs.

Then, we can focus on the actual mechanism using real spectext rather than getting lost in rathole discussions about which auth approach is best.

The devil will be in the details for that extension mechanism. Whatever mechanism we choose may not be able to treat all options equally, but at least we can separate the debate about good v bad authorization strategies from the specific means through which we will support authorization.
