Compatibility of VL packages with Qlik Cloud Saas (QCS)

I understand that the write-back functionality doesn't work with QCS, and as a result the Collaboration Package is not compatible. 

However, is there a roadmap that plans to make it work ? 

I also understand Library package is compatible. 

How about Finance package ? as well as self-service package? 

Thanks a lot,
