I see that is_enabled is a method that is already established prior to this PR, but I'm concerned that it treats an explicit None the same as a missing key/value. Worse, now that I'm thinking of it, any explicit value that evaluates as false-like. This is IMO a bug waiting to happen.

The way I'd deal with it:

• establish a module variable MISSING = object()
• condition becomes if required and settings.get(key, MISSING) is MISSING:
