why not?

None of those levels' definitions are set in stone; you can completely
change their meanings, or delete them, if you please.

or, you can ignore them, and implement a single rc-like script, using
only two of them (one for single-, one for multi-user).


The system gives you the flexibility to configure things to do as you
please; indeed, i've seen systems which had 'single-user with
networking' (so that you could set the console to a pseudo-tty, and
have that user be logged in over the network, e.g. to do remote
maintenance).
