The problems are:

 * Loss of compatibility; sysvinit users moronically expect to be able
   to invoke "init" on the command-line, and get "telinit" (this is done
   by checking the pid)

 * The (unimplemented ;p) facility to supervise daemons that fork would
   not work, all jobs would have to run in the foreground and use some
   other mechanism to indicate that they are "ready"

 * Security decisions about process-to-process initctl messages, and
   having to give the pid of the control daemon with every command

That's not to say this is impossible, just explaining why it doesn't
work like that out of the box right now.  We've been thinking about
"user upstart processes" as a replacement for things like gnome-session
