It's about reducing the amount of water used.
Hoses allow, and even encourage, a much greater use of water when it's in short supply, and aren't used a lot when it isn't in short supply.
Some people don't have hoses as they don't have an outside tap and repeated use of a hose from an indoor tap will catch up with you at some point...
Fair point. And yeah, I had a run-in with the concept of the double-stop valve recently when replacing my garden tap...
