pydantic Field extra deprecationwarning is not clear

Initial Checks

• I confirm that I'm using Pydantic V2

Description

if i start my project i see Deprecationwarning about extra kwargs in Field declaration.

PydanticDeprecatedSince20: Extra keyword arguments on Fieldis deprecated and will be removed. usejson_schema_extra instead. Deprecated in Pydantic V2.0 to be removed in V3.0. See Pydantic V2 Migration Guide at https://errors.pydantic.dev/2.1.1/migration/

I can't made any suggestion about model of Field if i have more than 40 models.

I solve it in fields.py - added next code after 783 row:

783:    if extra:
784:         warn(str(extra), DeprecationWarning)  # i add this warning to see deprecated extra kwargs.
785:         warn('Extra keyword arguments on `Field` is .....', DeprecationWarning)

it helps me to migrate to V2 faster.
I think it should exists by default
