The reason I want to go over the cases is some seem to think uma and oidc are all the use cases. As Justin points out they are very specific.
It doesn't seem like the dyn reg proposal is general enough to meet the wg charter's intent. At least from what i recall of the discussion. While i think some concepts in scim reg move things forward, i dont think it should move forward either. There should be one approach. Or failing that a strong taxonomy that makes it clear why multiple approaches are needed. Lack of consensus is not such a reason IMHO. I want to ask fundamental questions like what problem is being solved and what needs to be done for each client type. The assumption that client id must be issued by the sp seems wrong to me in many cases-- including oidc. 6749 does not make this restriction at all. Given this, a statement approach may be sufficient for many clients. No need for long term credential mgmt or records.
