> Currently, the support for client_id and client_secret treats the inclusion
> of the CLIENT_ID as a formality of the client credentials flow and since the
> actual client_id is resolvable from the client_secret, it is ignored.
> While there it may be arguable whether we need to enforce this, it seems a
> reasonable expectation that they should match. Let's close that gap.
> We may need to decide whether we want to make that configurable. Is there a
> feature hidden in there somewhere?
