Issue description
In the dev demo of project nucleus, it was mentioned that SPFx support was on the cards. I can't find any literature if or when this will be implemented.
More specifically I'd like to know if I can do the following in an SPFx solution:
Detect if we're in offline mode (e.g., I may not want to allow users to make changes in certain circumstances if I know that it will just be a local cache change)
Detect if sync is enabled and functioning on a list. If sync is not enabled, then I'll know that some queries won't work due to the 5k threshold, and can design the UX accordingly.
If sync is not enabled, is there a way to find out why? There is no clear guide on how sync can be enabled and to troubleshoot why it is not enabled so it would help if we can obtain the reason for sync not working.
In terms of the 5k threshold limitation improvement, would that work for libraries? Would there be a separate cache for the blobs and metadata? For example, a client may not have enough storage to offline the whole library but could have enough storage for the files metadata

Ashlesha-MSFT Vesa said it would be. When will it be supported?
