Just took the survey. Survey is poorly constructed. It should ask a few questions up front that segment the responses - end-user vs dev, techie vs non.

Most of the ~50 sites we manage are small businesses who really do not care about things like the customizer. They only care about running a successful business.

Sadly, that means one of the first things we do is strip out anything that does not serve that purpose. We then rename (effectively) and adjust many items so that they can be seen by the business staff in business terms. This means using CPT and/or custom taxonomies to make the site "Business Friendly".
