Comment:

 The history here is that these pages were kept for compatibility for users
 with JavaScript disabled when we deprecated the pages in favor of the
 customizer. The JS runs in the browser on load to hide the menu items with
 CSS. If they don't get hidden, it's actually probably because there's a JS
 error somewhere. There are several places sprinkled throughout wp-admin
 where similar logic applies for showing customizer links.

 `hide-if-customize` is essentially used as `hide-if-has-js`. The customize
 user capability is mapped to edit-theme-options by default, so users with
 access to the header and background should have access to the customizer
 also.

 At this point, can lose all of that logic and remove the links entirely?
 How many pages in wp-admin work at all with JS disabled?
