i re read what i wrote and i think i wrote it very confusingly(?), not sure that is a word, but i'm going with it
I would like to start with the UnifiedPushClient and remove the jQuery dependency from that. It would then return an ES6 promise instead, or you can still use callbacks.
i think this might be ok for a next release, 1.5.0, since the api is labeled experimental.
For datamanager, 2 out of the 4 adapters are labeled experimental, so we would not change the promises return type until 2.0
what i previously wrote sounded like i wanted to change 2 data manager adapters while keeping the other 2 the same.

This could be interesting, but i would like to keep things simple first
