I disagree.  (I'm good at that :).  K means that you want the program
stopped when going into that runlevel, but there is no point in trying
to stop it running every time you go into runlevel 3 when it wasn't
running in the first place.

S link - start program
K link - stop program
no link - no action

It won't confuse it.  Not at all.

If people want to keep the program installed but not started (which
seems like an odd thing when it is so easy to install & uninstall
software) then removing the link is the best idea.  If you want to
rename the link so that when you replace it you know what number it
used to be then I'd change the capital 'S' to a lowercase 's'.  This
way it won't be started or stopped, and you still know what number it
used to be.

But it doesn't make sense to keep trying to kill a program that was
never started.
