One thing this helps with is keeping development environments up to date. When there's a large spread between instance lifetimes, it becomes more difficult to deploy updates and changes to developer infrastructure. This can grow into an org problem where shipping dev infra changes blocks on disrupting dev workflows. You can approach this by continuously deploying upgrades to the dev fleet, but it's simpler to simply set a lifetime bound (with an opt-out for special circumstances).
