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.
