In fact SPA in general are suppose to work around a single issue, sending a request will lose all your state and reload the whole page(If different content, downlaod whole html). Since most website have multiple routes this is an actual issue. You need to sync state with server for example. I think the solution will be able to say "all this route are the same site" to the browser and now browser can be able to allow delta update or store some variables. This will be perfect with html imports.
