It's been known that Rucksack integration has been in the work for quite some time.

I had chat with Joris to find out where it stands and he mentioned that the integration is almost done except a few things.

This is what Joris said,

I believe Joris and you are talking over this matter but it seems that he will need some help from you to finalize the integration.UCC has an inventory abstraction so it should be easier to implement for custom inventory solutions like Rucksack; However, there appears to be some unintended behavior of equipping / un-equipping on start, as well as the method signatures being a little confusing to me

I'm bit worried because just like happened with FinalIK integration; I thought you were talking to Partel but it turned out that both of you were relying on each other for the responsibility

Anyway, earlier I had few problems with UCC inventories because UCC inventory system is very basic. I decided to wait until what Rucksack has to offer.

I hope you would support Joris to help finish the integration and I'll appreciate for your help on his behalf. ^^

Cheers!
