Roadmap - Loki in Multi user enviroment

Thanks for the pointer - it looks like there aren’t Org Ids within S3, just the directories for each tenant id.
As a follow up, how are the Org Id’s defined? I think maybe I’m conflating Grafana Orgs with what we’re talking about for Loki X-Scope Org ID.
Theoretically, what I’m trying to accomplish is defining a Loki data source for each Grafana Org and using the HTTP Header to access a single (or more) tenant id(s).
