Combined dev/test/prod in single orchestrator/tenant/service

Anyone using a single orchestrator tenant/service (enterprise or cloud) that covers both prod and non-prod? The environments function seems to be designed specifically for this outcome, but the blocker seems to be that asset values cannot be configured to be environment-specific. Robot-specific values is a workaround, but may not scale well. Otherwise the path from non-prod to prod is very clumsy and error prone.
Any experience out there?

I just read the Environments is effectively deprecated by Folders. But I also remember reading the Folders is only supported for attended robots, not unattended - do I have this wrong?
