Except that if people don’t know the feature exists, they might not ask about it. If you see the feature exists and you don’t want it, it is easier to figure out how to turn it off.
There are many feature that are turned on by default - this is just one of them.
But you don’t see all the people that does not ask for features, but could benefit from them. I worked IT support for years and I often suggested features or different workflow to users because I could see they were doing things that could be done easier.
