[aluong]

We should investigate what type of impact / pros / cons switching to these new SDK. We can file new items for doing the transition one by one in the future.

Duplicate of #4418. Closing #4418

@stefangordon and @aluong is this related to #4414 ?

[stefangordon]

I think both are good to keep. On #4414 I have already investigated and the work is pretty tactical (ready to do now). This one is for some of the SDK's that are still in preview and is more about researching if we should switch.
