But while the changes to Streams to support out-of-band and urgent data were
minimal, changing BSD sockets to support OSI or some other layered protocol
would involve much more work. And again, without a framework like
Streams, it would have to be done all over again for the next great
Protocol to be.

Conceptually, Streams is a clear winner. The implementation might not
be perfect, but then I never argued that.
