You say:
For those of us who follow core development and feature plugins with rapt attention, this new feature was not a surprise, but we are in the minority.

I think this is where the problem is: the balance between contributors and users seems dangerously low.

Even at the risk of being misunderstood, I would say that WordPress (as a project) should not be too concerned about what the users think.
WordPress (as a project) is not a company that must satisfy customers, instead it must listen to contributors.

As contributors are also users, you will still get the general idea of the trends in the so called user community.

User and contributor are not physical persons, they are roles:
- the user needs WordPress
- WordPress needs the contributor

Let's go and test the menu customizer
