I find the debounce default of 300ms to be quite slow, especially when changing from validating on input to on blur.

I changed it to 0 which serves my needs, but I'm unsure why that debounce is there, and whether I'm asking for trouble by changing it.

Why is there a debounce? Am I right in assuming it's specifically for the "validate on input" scenario?

(If so, I'll write up a little section for the docs...)
