If it's no effort, I would like to seem this on the trunk also.

In general, I'm skeptical about the "new features only in 3k" strategy.
Some features can be added easily with no backwards-compatibility issues
in 2.x, and would have normally been added to the next major 2.x release
without much discussion.
