we should probably also make that if better to see if enum is in value. this is the change in pydantic from const to enum.

[yarikoptic]

@satra : would that make it compatible with earlier pydantic versions, or it is an orthogonal issue and we could proceed with this one?

[satra]

i guess, we can impose whatever minimal version. i think it's ok for us to proceed with this.
