Pull back into Rake or merge newer versions of Rake in Drake?

[bias]

Has there ever been a discussion about pulling Drake into Rake? Or, to merge newer versions of Rake with Drake?

I'm starting to use Drake at work in a production environment and am interested in the future of the project. I realize opening an issue/feature request about maintainability isn't necessarily the best means of communication but prefer to keep the discussion open in case anyone else has similar thoughts.

We use it heavily in Passenger so I'm also hoping that this happens.
