Even with your proposal this would true during the entire development
period until the release candidate cycle starts.

It would be better for the policy to be able to become NEW right away.
We used to do this by introducing policies with the version set to
the current (dated) version of CMake.  IOW, instead of using "2.8.11"
as a policy's introduction version, one should use "2.8.10.20130203"
or whatever date introduced it.  We used to do this when introducing
policies way back when.  Then in the RC we bump the new policies'
versions to the RC version.

The entire point of the release branch is to hold the version number
adjustments needed for release candidates.  It should not be in master.
I don't want to get into a debate about how the versioning works.
