I'm going to use this issue to document the testing of testground/infra#78 performed on 2022-11-09. If you want to click around the dashboard, you can go to http://a106f6db4c1fa4eadb9c07cc0600af50-316085603.eu-west-3.elb.amazonaws.com/tasks. I'm letting it run for a while to see if the storage persists as expected.

I will be hiding my original feedback comments as soon as they're resolved.
