Extends QuerydslRepositorySupport problem

I do not understand why there is not any method to get MongoOperation object. When i extends that class then ok i have got all function for query but what about other crud operation such save and delete. Meybe best aproach is to set variable MongoOperation as protected or add new getter for it ? QuerydslRepositorySupport for JPA is more complex and user can get entityManager. 

Maybe also add new wariable for PathBuilder ??
