Change Summary

I don't know if this is expected, but doing the following:

from typing import Annotated, TypeVar

from pydantic import BaseModel, Field

T = TypeVar("T")

ExcludedField = Annotated[T, Field(exclude=True)]


class Model(BaseModel):
    run_path: ExcludedField[str | None] = None

Model.model_json_schema()
#> {'properties': {'run_path': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'default': None, 'title': 'Run Path'}}, 'title': 'Model', 'type': 'object'}
Model(run_path="a").model_dump()
#> {}

The field is still included in the JSON Schema. So either the docstring is incorrect or it should not be included in the JSON Schema as well?
