For a second, I wished there were a recycle-water button in my sink to rerun the flow-thru — I thought it’d be nice to have the water constantly running while cooking or cleaning up around the sink, so that I don’t have to touch the faucet knob with my covered-in-goo hands.

But then, it could just be a motion sensor button or pedal to avoid that problem. Also, a recycle-water button is probably prone to causing nasty accidents.
