PSGI isn't just about portability, it's also about middleware. With a 
common interface between components we get out of the rut where each new 
cool plugin was re-implemented by every existing framework. Now most 
things can just be written as PSGI middleware and anything can use it no 
matter what your framework (or lack of one).

For instance, these are some handy ones to have:

Plack::Middleware::InteractiveDebugger
Plack::Middleware::REPL
Plack::Middleware::Firebug::Lite
Plack::Middleware::JSONP
Plack::Middleware::RefererCheck
Plack::Middleware::Static::Minifier
Plack::Middleware::HTMLMinify
Plack::Middleware::Mirror
Plack::Middleware::iPhone

And there's a ton more. Yes lots of them can be done with other existing 
Apache modules (but not all of them) and lots of them might already 
exist in your framework of choice. But pulling things out into 
middleware seems to be the future of such work and will thus get new 
features and be better maintained than lots of other alternatives.
