The client may have a developer key which is a bearer token.   How it gets it is out of scope,  however we do see in the real world developer portals where developers establish accounts and get keys/tokens for creating clients.

Depending on the IdP this master token could be issued to a native app and then used to create separate client IDs for each instance.

The spec allows a client to have a token for registering or arrive without it.    Like OAuth punted on how the client gets a ID and secret, we are punting on how the developer gets its initial token if it is required.

There are real use cases for this in API management.   It would be nice if those systems could leverage this spec rather than being forced to create something different.
