When iOS 14.5 is released, is use of ATTrackingManager required only on iOS 14.5+?

I have some library integration sample that looks like this:

Code Block 
if (@available(iOS 14, *)) {
        [ATTrackingManager requestTrackingAuthorizationWithCompletionHandler:^(ATTrackingManagerAuthorizationStatus status) {
            [TenjinSDK connect];
        }];
    } else {
        [TenjinSDK connect];
    }

(It was written at a time pre-14 when Apple stated ATT would be required in 14.0) Now that ATT is going to be required in 14.5, would it meet Apple requirements to update the first line:

Code Block 
if (@available(iOS 14.5, *)) {

?
