The startup time is something that IMHO is a completely underappreciated feature of high quality systems. Starting a system in some configuration or other, taking a millisecond, completely changes the types and scope of tests that can be run, compared to when starting a component takes 30 seconds or so, which is not uncommon in [frameworks]

I completely agree. A lot of discussions about startup time just focus on the advantages it has in production - meanwhile the advantage on the testing side is way higher.
