Not exactly. The current setup was pretty stable up to –15. In –16 I tried to clean it up by moving the parameter into each token endpoint type definition. That didn't work and was more confusing so in –17 I reverted back to the –15 approach.
What makes this stand out in –20 is that all the examples now use HTTP Basic instead of the parameters (since we decided to make them NOT RECOMMENDED). So it feels sudden that client_id is gone, but none of this is actually much different from –15 on. Client authentication is still performed the same way, and the role of client_id is just as an alternative to using HTTP Basic on the token endpoint. I think the current text is sufficient, but if you want to provide specific additions I'm open to it.

I'm okay with the change but feel it's wroth mentioning that it's likely an incompatible one. That aside, I feel like it could use some more explanation in draft-ietf-oauth-v2 because, at least to me and hence my question, it wasn't entirely clear how client_id should be used for those cases.

If you are using Basic or any other form of authentication (or no authentication at all), you are not going to use the client_id parameter.
