I'm -1 for this feature. The right UI for clearing a select input is a clear button, not a clear option.

MUI has a discussion and instructions for implementing this in user land:

I agree that it makes more sense a clear button, but I tried to replicate the way it was in <SelectInput> and I also realized that it <NullableBooleanInput> is also that way with an empty field in the choices

I understand your reasonning, and it makes sense. However, for new features, we look for the best balance between intuitive DX and good UX. In this case, I think the balance clearly points to a clear button as adornment.
