Clearly there is a fundamental philosophical difference here. The end result
is pretty clear:
1. Every implementor except Caja is implementing CORS and prefers a unified
CORS/UMP spec.
2. Some implementors are unwilling to implement a separate UMP spec.

The same arguments have been hashed out multiple times. The above is not
going to change by talking through them again.

Blocking the CORS spec on principle is meaningless at this point. Even if
the spec were not officially standardized. It's shipping in browsers. It's
not going to be taken back.

Realistically, UMP's only hope of actually getting wide adoption is if it's
part of the CORS spec. Can you focus on improving CORS so that it addresses
your concerns as much as realistically possible?
