Why a fuel-cut rev-limiter?
Is there any good reason that Nissan selected to implement the rev-limiter as fuel-cut? Wouldn't ignition cut be just as simple to implement, and a whole lot safer?
Its just something that's always bothered me.

Cutting the ingition is not safe. If you continue to dump fuel with no spark, you saturate your cylinders and exhaust system with fuel. Then put a spark back and you have the possibility of blowing a head gasket from excessive cylinder pressure and a huge back fire in your exhaust system that can possibly blow your muffler apart.
A neat trick on a motorcycle is to keep your throttle on and hit the kill switch for a 2 second count, then flip the switch back on and you blow an explosion from your exhaust that rattles the neighbors.

I know all too well about blown mufflers from backfires (mustang). Also the gas > motor oil, so if you have a lot of unburned gasoline in the engine, it will break down the oil. Kind of why you never rev you engine then turn it off, you let it get back to idle for a few seconds.
