 This route will of course make the post meta table explode in size. I
 wonder whether we could serialize all the meta data for each post revision
 and store it in one meta field.

 The latest revision for each post could have its meta data copied over (so
 it can be used to display the correct post template in previews, etc) and
 every time a new revision is created we serialize the meta data in the
 previous revision and store it all in one meta field. This eliminates all
 the additional rows we'd otherwise see in the post meta table, and it also
 potentially allows us to revert a post's meta data along with everything
 else when a post is reverted to a previous revision.

 Thoughts?
