I agree, so let's see if we can get the ball rolling in that direction.

Some of the shortcomings I see with upstart that systemd sounds like it 
addresses are:

1)  The ability to drop back to single user mode for system 
administration.  Upstart can not make sure that all processes started 
during multi user mode that are not supposed to be running in single 
user mode are actually killed.

2)  The ability to serialize state and re-execute itself so it can run 
in the initramfs and then hand off to the real system.

3)  The ability to figure out why a given service runs or does not run 
when it does or should.  Right now Upstart relies on comments being 
added to the config files to give the admin clues about this, but that 
is inherently unreliable and still difficult to figure out.

4)  The increased parallelism systemd offers by running services at the 
same time as those they "depend" on by having systemd create the socket 
is not something upstart currently can do.  I am not sure if it can be 
extended to do this or not.
