You don't really want to hang your hat on that argument, do you?  Or
are you using some form of text not represented by zeros and ones?
 Surely you can imagine a binary protocol in which some parts are
optional and that can be extended in ways that older clients can
ignore.  I know you can, because text *is* binary.  

Since the difference between "text" and "binary" is cultural
convention, neither one is inherently more or less capable as far as
the computer is concerned.
