I don't care what it is.  It just shuldn't be alowed.

Lot's of people do this.  Back in Win3.11 days we had the option of 
booting to a command line or putting "win" in your autoexec.bat.  
Few people did the later and nobody ever considered it hard to type
a 3 letter word to "get into the system".   Hell, the username 
+ password is longer than that and nobody has proposed getting rid 
of it.  What would be nice is to create a simlink from startx to 
win.  Just for fun :)
Now that I think about it some of the worst Win3.11 problems happened 
when Windows was screwed up and the machine insisted on starting it
anyway.  The user often knew just what to do to fix it ( she set the
resolution to 1024*768 so she can set it back ), but had trouble 
getting to a command line.  This means 3 or 4 hard reboots with all
the disk corruption that goes with that.  For Linux this shouldn't be 
an issue.  
Some things are <IMHO> too close to impossible for us to hang our hopes
on them being accomplished.  1, Is an unbreakable GUI.
It may be possible, but I wouldn't want SEUL to depend on it.
