Comment (by ocean90):

 Nice work in [attachment:35658.48.diff]. `register_meta()` still has a
 comment which references "subtype" (''Global registry only contains meta
 keys registered in the new way with a subtype.'') and
 `Tests_Meta_Register_Meta::test_register_meta_with_valid_object_type_and_object_subtype_returns_true`
 should probably be renamed.

 Do we want to add support for "some sort of `WP_Object_Type`" now? We'd
 only have to cast the `$object_type` to a string:

 {{{#!php
 <?php
 class Foo {
         function __toString() {
                 return 'foo:bar';
         }
 }

 $foo = new Foo();
 $a[ $foo ] = 'a'; // Illegal offset type
 $a[ (string) $foo ] = 'b'; // array(1) { ["foo:bar"]=> string(1) "b" }
 }}}
