Does being "inefficient" really matter for a washing machine if you don't live in the desert? Its not like they go through 100+ of gallons of water or ridiculous amounts of electricity even in the worst possible case scenarios.

Actually old top loaders aren't so far off of that number. Maybe 40+ gallons per load.

But still I'm inclined to agree with the general sentiment of not micro optimizing things in ways that make people's lives more difficult.
