"Oh no, they’re not… are they?" It seems fairly sensible to me to double up the lighting leds as diodes, from an extreme cost-engineering perspective. Of course, it does mean you can't turn the lighting off ... I have an optical-switch k/b. If you need a diode per key anyway you may as well have an optical sensor instead, and have no key debounce, it could be waterproof, spark-free, separation of concerns between sensing and the mechaical switch itself for easy hot-swap switches, etc. To me it's the obvious future, but it seems true mechanical k/b fans aren't with the program yet.
