Could a new ActiveRecord/ActiveSupport pair be released independently
of Rails 3.0, for use with 2.x apps? Maybe make a Rails 2.4 release
that is 2.3.5 plus new ActiveRecord/ActiveSupport?
This way 2.x apps could get the benefits of the new AR interface, and
in this way also migrate toward 3.0 in steps, if they’re not ready to
upgrade all the way to 3.0.
Since all of the changes are isolated to ActiveRecord/ActiveSupport,
would this be possible?
