r=me, but I find this way harder to read.

How about switching to ObjC literal syntax? You'd end up with something like:

    RetainPtr<NSMutableDictionary> newPolicies = adoptNS([policies mutableCopy]);
    [newPolicies removeObjectForKey:@"apple.com"];
    newPolicies.get()[@"google.com"] = @{
        @"com.macromedia.Flash Player.plugin": @{
            @"26.0.0.126": @(kWKPluginLoadClientPolicyAllowAlways),
        },
        @"com.apple.QuickTime.plugin": @{
            @"1.0": @(kWKPluginLoadClientPolicyBlock),
            @"1.1": @(kWKPluginLoadClientPolicyAllow),
        },
    };

I like this better, but it has the (slight) disadvantage of putting all the objects in an autoreleasepool.

I'll switch to adoptNS().get() instead, as we talked about in person.

Readability seems *so* much more important than putting a few objects into the autorelease pool.
