I don't think you're framing the issue from an educated standpoint. You're confusing high-availability with not designing a brittle service by paying attention to very basic things that are trivial to do. For example, supporting very basic blue-green deployments that come for free in virtually any conceivable way to deploy services. You only need a reverse proxy and just enough competence to design and develop services that can run in parallel. This is hardly an issue, and in this day and age not being able to pull this off is a hallmark of incompetence.
