Can't have pages with children render correctly: routes: { page: ':link',

routes: {
page: ':link',
post: '/media/:year/:month/:slug', //adds route for "post" post type (Optional)
post_tag: '/tag/:slug' // adds route for "post_tag" post type (Optional)
}
Doesn't work.
routes: { page: ':link_raw', }
is close - but the / character comes out as URL decoded %2f.
E.g. all the links are:
mysite.com/toppage%2fsecondlevel%2fthirdlevel

So can only have /pages/:slug which is not SEO or structured (especially for 3-4 level deep websites).

Goal would be able to replicate wordpress page structure
