if you're not using test-resources.json, please do tag your resource group(s) with a DeleteAfter tag and a value like ISO 8601 (IIRC) that is typiclaly +24hrs, so like "DeleteAfter=2020-04-25T02:00:00Z". This is so that resource cleanup scripts EngSys runs deletes them automatically.

Putting in P3 for now but really just needs to be tracked and done sometime before GA
