I'll bet in most households no more than 3 settings will be used.

Agreed!

In my household its either short or long wash at 30C or an occasional
wash of (towels) at the highest temperature.

Yes, the usual 'every day' wash, a hot wash and a quick wash.

I have given up looking at specs for domestic appliances now, and just
buy whatever is on offer at the time. They all do the same basic job
whether fridge, washing machine or whatever.
