We used the metaclass EnumMeta/EnumType to override reporting of missing enum values (to give the full set of supported activations). However, in Python 3.12.3, the default value of the name parameter of EnumType.__call__ method was changed from None to _not_given:
Even though this is a public API (which now uses a private default value), it seems too risky to continue using it. So in this change, we implement Enum.__mising__ instead for the improved error reporting.
