As you can see this creates an awkward situation. I'm sure there

such devices as well e.g. counterfeit Logitech keyboards, USB serial

world the support would live in another driver, but since in case of
this "fake" PS3 controller it "share" our product / vendor ids it is
tricky. At this point there is not a strong enough case yet to
augment
the "hid-quirks" to do so, but perhaps if it became a serious issue
(e.g. for newer controllers) maybe we need to think of something.

I'm pretty certain that the only reason why those use "fake" VID/PID
combinations is because that's the only thing the consoles will
accept. 

That's par for the course when you try to close off your ecosystem that
those that try to enter it will use the means at their disposal to do
that.
