PydanticMixin doesn't have super() call which leads to issues with decomposition.

At the moment, plugin code is organized in the way, where main logic is keep the same, but additional logic can be added using decomposition with Mixins.

The behaviour supposed to have chain of super calls in each of Mixin class, to apply each of visit function, if required by option.

At the moment, PydanticMixin implemented without super call, which leads to heavy dependence on MRO for future mixins.

For my opinion, it should be resolved by adding super call to Pydantic Mixin (quick solution), or changing the decomposition pattern.
