There is also the "old" cosign, but I don't know if we want to remove it afterall

Good shout - we can discuss that at some point. I think it depends a bit on who's actually using it?

@vaszig you can pick up removing the old appointments integration

Objects API/ZGW groups shouldn't have fields nullable

@sergei-maertens the only field that is nullable from what I can see is objects_api_group in ZGW registration options: https://github.com/open-formulieren/open-forms/blob/master/src/openforms/registrations/contrib/zgw_apis/options.py#L114

Should this be required?
