The changes make sense to me. I will adapt what I have done in Spring Data Cassandra to fit this as well. I have a couple of comments but other than that LGTM.

The interface resolution when generating the <repo>.json file seems to be a little off for a repo interface that uses methods delegating to the default repository implementation when not using one of the predefined repository interfaces.

interface OwnerRepository extends Repository<Owner, Long> {
  void save(Owner owner);
}

{
  "name": "save",
  "signature": "public abstract void org.springframework.samples.petclinic.owner.OwnerRepository.save(org.springframework.samples.petclinic.owner.Owner)",
  "fragment": {
    "interface": "org.springframework.data.mongodb.repository.support.SimpleMongoRepository",
    "fragment": "org.springframework.data.mongodb.repository.support.SimpleMongoRepository"
  }
},

Yeah, I have no good idea to fix that yet. The interface in fragments refers to the type that contributes signatures when looking up methods. For Querydsl and fragments, that is the actual interface. Maybe we just suppress interface if the fragment is the same as interface.
