You know, I've been thinking about all of the bipolar opinions of Default Themes for WordPress (primarily necessary for WordPress.com users) and have come to the following conclusion:

Why not have the core developers create an Official WordPress Theme Builder; designed and maintained for WordPress.org users only, packed full of Customizer Options, placed on GitHub, and built on the foundation of Underscores (or any other base core structure maintained by the core developers).

The reason I would like to see this take place is that Themes designed by Automattic always seem to be niche oriented, and most of the time are purposefully limited in Customizer Options. I installed the current GitHub version of Twenty Sixteen, and two things already irritated me and guaranteed that I would not use the current of that theme:

1. The main Blog Page displayed all Posts as full displays including Featured Images, which delayed and overburdened the initial rendering of that page. There was no way to set the Blog Page to only display excerpts in the Theme's Customizer (although many Commercial Business Themes do offer this option as a checkbox in their own Customizer).

2. Twenty Sixteen (as of right now) does Not offer Full-Width display in either Pages or Posts.

I realize that the above two options are MY desires and maybe not those of others, but to satisfy WordPress.org end-users, why not provide a way for them to modify their chosen WordPress Themes AS THEY SEE FIT.

I also realize that third-party Theme Builders already exist, but why not have an Officially Supported WordPress.org Version that will never have compatibility issues with the core components?
