 Why is the same jQuery script added twice, with only the `'jquery'` handle
 referenced later?

 > there are 11670 plugins and 1144 themes

 Despite the wide variety of plugins and themes in the repository, let's
 keep in mind those available from other sources, the authors of which may
 not be contactable by email like wp.org authors. Specifically for themes,
 I'd say that's the majority of sites out there.

 Either way, step 1 is to ensure that WordPress works correctly with the
 latest standard theme and no plugins. Then, there should be a way for
 specific site owners to enable jQuery and/or Migrate specifically for
 their site, until most people adapt.

 Ultimately, isn't this like any deprecation?
