You can't expect new functions so fast just because you ask for it here. Mikrotik will promise nothing, but one day, maybe, you can be surprised. But it will be far after you realised the project with different software...
I know this
I've been working with Routerboards since ROS 4.0 was announced. But, as you said, sometimes you can be surprised - so as with CAPsMan, which we were able to implement for a large installation last year becaus we joined the Beta tests and two days before mounting the APs the final release came out.
So I'm waiting for auth with certificates with patience and since then I use openWRT instead...
