Not really - there is tremendous advantage even for large content providers to be able to use the same infrastructure to scale the service as is already deployed for the web - namely standard web servers and caches as already deployed in the CDNs. Restricting server extensions to the origin servers is an option, but then you lose cache efficiency, since when the server prepares the same data in two different ways for two users it gets cached twice.
