http_method_names and @action decorator

[variable]

I had a task to add an extra action to an existing ModelViewSet view, to simplify the example:

class UserViewSet(ModelViewSet):
    ....
    queryset = User.objects.all()
    http_method_names = ['get', 'post']

    @action(detail=True, method=['delete'])
    def delete_profile(self, request, pk=None)
        Profile.objects.get(user=pk).delete()
        ....

when I make a delete method call to /user/123/delete_profile, I get 405 Method not allowed, however, if I add delete to http_method_names as below, it works fine.

This is because delete is not in http_method_names. But having delete in http_method_names it implicitly allows delete operation on User model, which is wrong.

I am in two minds:
1st) This is by design that a ModelViewSet should only manage ONE model
2nd) But then my above case sort of makes sense to delete related model as well

Could someone please provide some guidance on this matter? Should method inside @action override the http_method_names?
