For a mouse and a keyboard this for sure intended. Both act as input device like the power key and therefore can activate the device. For example when I have the tablet or the phone working as a converged device I as a user want the device to go to sleep when I wake up but be back when I active either one of those input devices (power-button, mouse or keyboard).

That the device wakes up from a deep-sleep is something we can't prevent and really shouldn't. If I turn on my paired headset I expect it to be usable no matter what state the other device is in. So connection establishment is fine here.

What we should fix is the use of the proximity sensor or other sensors to find out if the device is in a state where a turned on display is intended (like it being in your pocket or somewhere else).
