Yes, there are certainly CGI implementations in use right now which don't use
stdio streams - for example, CGI scripts using Visual Basic (which has no
concept of stdin/stdout), or scripts implemented as DLLs. DLLs don't use
environment variables either. This is not perversity, it is just that those
mechanisims are not appropriate to these types of script.
I believe it is very important to keep the CGI standard as general as
possible. The standard should not include *any* reference to implementation
details of how the server identifies and communicates with the CGI program.
Separate platform-specific specs should do that. So, avoid
implementation-specific terms like "environment variables", and call them
(say) "CGI variables" instead.
