Adding my stamp of responsibility here. This is purely for a demo and some if not all of these changes will be reverted soon.

This PR will not be released.

This PR is going to be reverted after a demo on dev.coder.com. It is being demonstrated in a product demo to introduce Workspace Sharing among another set of demos on the same deployment.

The feature is gated on an experiment flag, so has no effect in any existing deployment. None of this code is reachable without the unsafe experiment specifically opted into.
