The problem is that sys.stdin and sys.stdout default to
TextIOWrappers, and handling protocols requires bytes, so having a way
to drop down to bytes is very convenient. Doing it by command line
arguments to Python works as long as a command is always byte
orientated (or never) - but thats a very big hammer.
