Alright. I bite: if it would not be done that way you had different 
problems.  In particular a problem that comes up very often is that 
people want the PATH_INFO and SCRIPT_NAME to not be encoded.  That 
however completely breaks any form of routing you would want to do the 
moment they contain unicode characters.

I keep having the argument about PATH_INFO and the header semantics 
constantly with people and i'm absolutely convinced (from the theory 
behind it as well as playing around with ideas for PEP 444 a few years 
ago) that it only gets worse the moment you leave the WSGI territory too 
far.

Likewise I wonder how many people that ask for more low level access 
concerned themselves with chunked requests/responses, transport 
encodings and all the complexity that servers do for you.  Yes, quite a 
bit of this is broken in WSGI but would have been trivial to fix without 
throwing the whole specification into the toilette :)
