OAuth logoThe OAuth 2.0 Token Exchange specification is now RFC 8693. The abstract of the specification is:

This specification defines a protocol for an HTTP- and JSON-based Security Token Service (STS) by defining how to request and obtain security tokens from OAuth 2.0 authorization servers, including security tokens employing impersonation and delegation.

This specification standardizes an already widely-deployed pattern in production use by Box, Microsoft, RedHat, Salesforce, and many others. Thanks to all of you who helped make a standard for this important functionality!
