Comment (by Looimaster):

 I've just read the whole discussion and properly written themes and
 plugins use correct dependencies and they seek the best performance.
 Therefore, I suggest doing it in two steps:
 1) Add `jquery_in_footer` filter or `wp_modify_registered_script()` which
 would allow to set `in_footer` to `true` for all the libraries that don't
 have it set to `true` at this moment.
 2) Remove this filter or function in the future and make it become default
 behavior.

 Is there any situation in which a developer should not load scripts in the
 footer? If there isn't then they should learn this or don't write code.
 95% of properly written websites should suffer lower performance because
 5% of developers are doing it wrong?

 Another idea: add ability to add `defer` attribute to jQuery `<script>`
 tag.

 Another idea: introduce `wordpress-edge` or `wordpress-strict` (like
 JavaScript's 'use strict') option that when set to `true` by a theme (not
 by plugins) would set all things to HTML5, to strict standards and the
 newest and the best practices. When set to `false` (default) it would work
 like it used to work.
