I was thinking along the same lines. So, do I always need to change the signature of that method to be
public PagedResult<OperatorList>
instead of current implementation?

Will I also have to change the repository interface as well?

Our application is quite complex and I am a bit confused as where should I made the change exactly.
If it's not broken, fix it until it is.
