Summary:

This specification describes a standardised protocol for requesting and
receiving security tokens from an OAuth 2.0 authorisation service.

I had no experience on OAuth previously, but the document was understandable
and as far as I could determine, had no major issues.

It was a bit more difficult to determine completeness.  Security and privacy
considerations sections were quite short, for instance, and maybe that's
justifiable given the ability to refer to prior RFCs on this subject. However,
I suspect one could say more, e.g., Section 7 says "Tokens typically carry
personal information and their usage in Token Exchange may  reveal details of
the target services being accessed", but it does not offer any advice on how
such details might be minimised. But perhaps that's already in another RFC as
well.
