Perhaps they did actually test it. Perhaps the majority is like me and find it useful.

As mentioned I didn't know that I'd like this feature. I wouldn't have reached for such an extension.

It's obvious that you don't want this functionality - which you can now easily disable. What if the majority of the users actually like this? Or the majority either like it or are not the slightest bothered by it? Is it not a good addition overall then?
