Breaking the world for the sake of making a few #include directives
more pretty doesn't sound decent to me.

Breaking the world to get rid of old crap (e.g., connect_port(),
control ports) would be interesting, but I doubt any user/developer
wants that. However, if it is the time for it, I'd like to sit at the
table and contribute my part.

P.S.: yes, I am still alive, just not kicking... and I still care somewhat.
