Work for this feature is now being planned. Will update when work on this feature starts and when it becomes generally available.
We are currently working on a new way to encode data that will both improve query scan performance and decrease storage size.
Will update once this is available.

We need this also. The 50GB per shard limitation is severely impacting our ability to scale. To give you an example we could have easily supported a tenant with 160K users in a single 1mil RU collection but Because they would require 50TB of space we can only fit 17K of that tenants users. We need either 10x storage savings (using compression for example) or shards with 10x more storage i.e 500GB cosmos shards.
Work on this feature has started. Will update again when complete.
