Yea. Fun, but not optimal for a product. 1000Hz is already comically faster than any human muscle reaction.

With regards to latency: reaction time is the wrong thing to compare against, since input latency can be noticeable even when it is much smaller than a human's reaction time. And wanting to have your keyboard latency be no worse than 1ms can make sense given that it's only one of many components of the total input latency of a computer. Reducing mouse or keyboard latency from 8ms (125Hz) to 1ms (1000Hz) is pretty much the low-hanging fruit; it's not as cheap or easy to squeeze 7ms out of the other parts of the chain.
