Comment (by azaozz):

 Thinking this may be a "not-so-great" UI change. Two reasons:
 - The whole Edit Post screen still has the feel of a form, and the
 submit/save buttons on most forms are not disabled when the forms are
 "empty".
 - We can (probably) detect changes in all metaboxes (they are saved
 together with the post, see [#comment:2 comment 2]), but may miss changes
 to elements added by plugins, especially when done with JS. For example:
 {{{
 jQuery( '#post' ).submit( function() {
   if ( [some condition] ) {
     jQuery( '.my-field', this ).val( 'My Value' );
   }
 });
 }}}
