Yes, it's fine, because an application developer can often control (or at least study) the behaviour of all the code involved.

I'd rather not have to check if some library messes with that global setting and work around it if it does! The fact that you can control and work around a global setting that may change, isn't a reason to introduce that global setting and the increased complexity that comes with it.

It's the same story as with logging configuration and similar process-wide settings. Libraries shouldn't mess with it but the top-level application definitely can (and should, even).

That's a bad comparison, because the situation is quite different with the logging module. Configuration of the logging module does not change the behaviour for code calling into the logging module (well, besides log output being produced somewhere, but that doesn't matter for the caller).
