Of course there is certain problems associated with taking away the main
user interface. However, the _only_ binary that a unix system commonly
depends upon is /etc/init.
In most implementations of init, a number of shell script is executed to
do the system setup, but this could be changed to executing binaries
quite easily (actually, it does execute whatever is there, so you wouldn't
even have to change init, just replace the shell scripts by matching
binaries).
Init then starts some sort of getty process for each line (or console),
which is a binary. The getty process, upon receiving a login name, starts
"login", which, again, is a binary. Upon successful login, "login" starts
whatever "shell" is given in /etc/passwd for that user, which might as
well be some sort of GUI.

Now tell me, except for the easily corrected instance of setup scripts,
where does a shell come into play?
