And that's my big issue. Moving everything to the customizer (widget admin, menu admin), and then removing them from the admin dashboard, thereby forcing everyone to use the customizer no matter what is a horrible idea.

But they've already said that's where they're going towards, in an effort to clean up the admin dashboard by making the entire thing be the customizer by the time WP 5.0 rolls around, I guess.

If they want to experiment with making the customizer be the default method of managing a blog, that's fine. It's not a good way to manage more complex WP sites, and no one seems to be listening to the many voices that are saying "add what you want to the customizer, just don't take away the regular admin menu options".
