Comment (by peterwilsoncc):

 Replying to [comment:4 SergeyBiryukov]:
 > These may be harder to remove, as the themes must remain compatible with
 older WP versions they were released in, and possibly one or two versions
 before that.

 The `jQuery( callback )` technique was
 [https://api.jquery.com/jQuery/#jQuery3 added in jQuery 1.0] prior to
 WordPress's introduction of jQuery 1.1 in [4904] so I think removing the
 `jQuery( document ).ready()` statement on the older themes should be fine.

 If I am missing something then the older themes may be able to use
 something along the lines of:

 {{{#!js
 if ( document.readyState !== 'loading' ) {
         readyCallback();
 } else {
         window.addEventListener( 'DOMContentLoaded', readyCallback, false
 );
 }
 }}}
