I gave a longer response regarding suitability of ALPS in that thread. As did Cory.

I can see how you might choose to opportunistically use ALPS, but I don't think that you can add it trivially to HTTP/2 implementations.  It's more of a case of not wanting it than it being functionally impossible; we could likely make anything work if we assume good integration of stack layers, but that isn't how HTTP/2 has been deployed and retrofitting something in that way would only result in a privileged few having the capability.  I would rather see it deployed for new protocols than try to have its presence alter how this existing protocol works.
