The LEDs on the G27 are very much more specific, mounted on the yoke of
the gaming wheel.

Would this require the use/complexity of the LED subsystem?

Well, it'd mean that applications that know how to drive LEDs will be
able to use the LEDs on this wheel with less per device knowledge which
seems like a useful thing and if someone wants to remap a LED to "new
mail" or whatever that'll be easier (nethack has the mailer daemon
deliver a scroll of mail!).

I'm not familiar with the LED subsystem, but my concerns would be that
this would add a whole load of code to implement.

Not really, it's rather simple to use and as Mark said, it's a proper 
infrastructure to use here.

We already have HID drivers which are using this -- you can look at 
PicoLCD or Wiimote drivers and you'll see that it's indeed fairly simple.

PS. I don't really care about email when screaming around Laguna Seca ;-)
