And so failure is a user mistake, not a programmer mistake, and should be handled as such. The programmer and the user being the same person is irrelevant.

The difference is that the config is loaded at bootstrap stage - if it fails, starting service fails, there is not much to handle other than crash and supervisor (ie. k8s or whatever) will try to start it again.

You would likely exit. Crashing on invalid user input would be nonsensical.
