It's no longer necessary, creates lots of unnecessary CLI commands and overrides some existing/better behaviours. Anything identified that is positive, it should be moved to mgr_module level (or mgr_utils) so that other modules can benefit from it.

Perhaps a possibility would be to replace MODULE_OPTIONS with a class that provides better functionality and encapsulates code:

MODULE_OPTIONS = ModuleOptions([
 Option('foo', int)
])

...

self.MODULE_OPTIONS['foo'] = 'bar'

print(self.MODULE_OPTIONS['foo'])
>>> 'bar'

• If option runtime is False, the value is fetched at the beginning and cached since then.
• Provide mypy/typing hints/generics.
