Of course there are use cases, but _ideally_, most workloads are staged, deployed, and backed up in such a way that it is a documented, reproducible procedure to tear down an instance of a server, rebuild, and redeploy services.

And while it may be cumbersome or cause some downtime or headaches if that isn't the case, I find the very need of doing it once every 1-3 years forces your hand to get your shit together, rather than a once per decade affair of praying you migrated all your scripts manually and that everything will work, as your OS admins threaten your life because audit is threatening theirs.

How many simultaneously running machines can you keep updating with this method? If you run non-trivial workloads for hundreds of customers, this becomes high maintenance system already with two machines. It takes ages to upgrade all applications, then validate everything works, then actually migrate with no downtime.
