use of allow-query-cache

[Allen Wooden]

I just upgraded my nameservers to 9.4.1 and wondered if
there is any reason I should change my current
configuration.  Is there some future change coming down
the road that would prompt me to change it?

Or is this just convenient to put it in the options statement
rather than put the allow-query in every authoritative zone?


options {
          allow-query { acl; };
          allow-recursion { acl; };
};

zone "blah.com" {
     allow-query { any; };
};

to


options {
          allow-query-cache { acl; };
          allow-recursion { acl; };
          allow-query { any; };
};


zone "blah.com" {

};
