When did I ever say that you would need to "merge" your SPA with an API server? I didn't, because you don't, because, like I said above...

This was in response to your earlier statement "At the expense of coupling which is not a trivial concern." Do you have any additional arguments for why adding a type schema introduces additional coupling that were not covered above?
