Comment (by greenshady):

 As I really dislike the idea of the initial proposal making it into core
 (it'll break several of my child themes and probably others that have been
 using theme mods for years), I've been thinking of a possible solution for
 theme authors who want to opt-into this functionality.

 Here's a quick bit of code that I was thinking about for theme authors.
 It may need some tweaking (untested).

 {{{
 add_action( 'switch_theme', 'jt_switch_theme_update_mods' );

 function jt_switch_theme_update_mods() {

         if ( is_child_theme() && false === get_theme_mods() ) {

                 $mods = get_option( 'theme_mods_' . get_option( 'template'
 ) );

                 if ( false !== $mods ) {

                         foreach ( (array) $mods as $mod => $value ) {

                                 if ( 'sidebars_widgets' !== $mod )
                                         set_theme_mod( $mod, $value );
                         }
                 }
         }
 }
 }}}
