The linked PR generates ref definitions at all json paths and includes example in a client sample spec where one component $refs another component.

this it is working in the v2.0.0 release of openapi-json-schema-generator.
That is where further development is being done on the python generator.
Here is the definition of the component schema RefPet

    RefPet:
      $ref: '#/components/schemas/Pet'

And here is the generated class

from petstore_api.components.schema import pet
RefPet = pet.Pet
