Disable a method in a ViewSet, django-rest-framework

The definition of ModelViewSet is:

class ModelViewSet(mixins.CreateModelMixin, 
                   mixins.RetrieveModelMixin, 
                   mixins.UpdateModelMixin,
                   mixins.DestroyModelMixin,
                   mixins.ListModelMixin,
                   GenericViewSet)

So rather than extending ModelViewSet, why not just use whatever you need? So for example:

from rest_framework import viewsets, mixins

class SampleViewSet(mixins.RetrieveModelMixin,
                    mixins.UpdateModelMixin,
                    mixins.DestroyModelMixin,
                    viewsets.GenericViewSet):
    ...

With this approach, the router should only generate routes for the included methods.
