If you have a mobile app that needs to do the code flow... which 
requires a client_secret in order to retrieve the access token and 
refresh token, how does the app do this without per app instance 
registration?

I'd argue that almost all user facing mobile apps will want the above 
flow and that's not a small, rare edge case.

To me, that is a vitally and fundamentally important use case that we can't disregard, and we must have a solution that can accommodate that. The notions of "publisher" and "product" fade very quickly once you get outside of the software vendor world.
