> "fast, ephemeral, concurrent dev environments" seems like a superb idea to me.

I've worked at one (1) place that, whilst not quite fully that, they did have a spare dev environment that you could claim temporarily for deploying changes, doing integration tests, etc. Super handy when people are working on (often wildly) divergent projects and you need at least one stable dev environment + integration testing.

Been trying to push this at $CURRENT without much success but that's largely down to lack of cloudops resources (although we do have a sandbox environment, it's sufficiently different to dev that it's essentially worthless.)
