Are you suggesting a "``str`` for headers, ``bytes`` for bodies" 
approach instead?

I suppose that could work; I was going for "str in, bytes out".  My 
assumption, though, was that headers are relatively easy to address 
at a choke point from a framework's output.  But I guess that 
iterator output is equally chokable.

I'm open to discussion on this point, so long as every value produced 
or consumed by a WSGI application is of a specified single type().

Um, if by "links" you mean, "included textually in the proposal", 
then sure.  If it's not in the proposal, it's not going in the PEP, 
even if it's on the WSGI Amendments page or Graham's blog.
