Comment (by westonruter):

 Aside: we need to make it easier to work with setting values that are
 objects. The usual pattern to update a setting with an object value is:

 {{{#!js
 var value = wp.customize( 'foo' ).get();
 value = _.clone( value );
 value.someProperty = 'bar';
 wp.customize( 'foo' ).set( value );
 }}}

 The cloning is needed because objects are passed by reference. So
 `Setting.set( value )` should be updated to automatically clone any object
 passed as its value argument, so you could replace the above with:

 {{{#!js
 wp.customize( 'foo' ).set( $.extend(
     {},
     wp.customize( 'foo' ).get(),
     { someProperty: 'bar' }
 ) );
 }}}

 We could also consider adding a `Setting.extend( obj )` which would take
 any properties in `obj` and set them on the existing cloned value, in a
 way similar to `jQuery.extend()`. You could then replace the above with:

 {{{#!js
 wp.customize( 'foo' ).extend( { someProperty: 'bar' } );
 }}}
