Why PSGI/Plack instead of HTTP::Engine?

HTTP::Engine was a great experiment, but it mixed the application interface (the request_handler interface) with implementations, and the monolithic class hierarchy and role based interfaces make it really hard to write a new backend. We kept the existing HTTP::Engine and broke it into three parts: The interface specification (PSGI), Reference server implementations (Plack::Server) and Standard APIs and Tools (Plack).
