Is this installable with CB 1.2?
Yes, you should re-build apache, to get all the benefits of the new version, if you use Apache 2.4.x with CB 1.2:
Not too sure whether it is possible to use apr-util 1.5.2 with Apache 2.2.x; and it seems it's rather not possible.
And is it something that is worth the upgrade?
Yes, just check the links in the first post here in the thread
