You've said this many times and it seems that you do it to be
obstructionist.  The constructive way to deal with this is to start making
a list of what people really mean by "essential" and then propose alternate
words to use.

I think, by essential, some people mean:

start the bare minimum so I don't have to start any additional services to:

... I don't want anything but init and a shell [*]
... log into a getty
... log in over the network
... log into a desktop
... do any client-side operations

[*] This one (but not limited to this one) also specifies that additional
services would be started, just not by packaging.  ie: the installer or
something else will start additional services independent of packaging.

I'll note that with both traditional SysV runlevels and the set of systemd
targets that we'll give to people in F15, we can have multiple defintions of
what services to start as well.  The rescue target (formerly runlevel 1)
would be different from the multi-user target would be different from the
graphical target.
