Inherit configs in pydantic v2

[ilija-lazoroski]

Hey,

In version 1 we could do the following:

class ImutableConfig:
    class Config:
        allow_mutation = False
        extras = Extra.forbid

class MutableConfig(ImutableConfig):
   class Config:
      allow_mutation = True

I don't really see a way to do a similar thing using model_config: ConfigDict.

I have the exact same problem with a very banal issue, how can I change the "title" value in the config:

from uuid import UUID

from pydantic import BaseModel, ConfigDict

class Base(BaseModel):
    model_config = ConfigDict(
        from_attributes=True,
        populate_by_name=True,
        title='parent'
    )

class BaseId(Base):
    id: UUID

class Child(BaseId):
    pass

how can I give a custom title to the class Child?
