Hi Kacey. To answer your questions:
• The global environment toggles act as a kill switch. So if something breaks with a feature, it's one place to completely turn it off. If we leave override rules always active, there would be no easy way to turn everything off quickly.
• For additional metadata, we kind of support that now using other data types like JSON for your features. Is that what you're looking for?
• Multiple environments should be coming within a week
• No plans currently for a streaming service
