Does it bother me that the light is on? Not really.
I mean with the latest firmware (1.7) they added the ability to turn the brightness down. So that it's a lot less noticeable. On the upside this should also increase the battery life by a bit also. (Since it shouldn't use as much power to make it brighter.) Even if this isn't quite a powered off...
I would still like the ability to turn it truly off though. I mean a dimmer switch is nice, but it's still using power. And even though, apparently, Sony's VR tech for the PS4 uses the light + ps eye... If users don't have/want to use that then they shouldn't be forced to keep their light on and drain their battery quicker.
