Thank you for a reasonable feature request.

- This is a request for an optimization that does not look to be widely applied. - Yet an implementation of this feature will take 2 man-months. By the above reasons I move the bug to 'To be fixed later'. Product management will decide in what version a fix for this problem appears.

does key cache or another cache help here? maybe it's not a 'problem' just a cache tweak
