Right, but that's a theoretical need not a real one.

Er, if you do -S twice then doing -N once should fix it as -N is the
opposite of -S.

I guess if you do -s twice then you can't fix it.  I'm not sure that is
a good enough reason to break existing scripts.

I think I can see why it would be vaguely useful but given it's going to
be used less than -S and -N I don't see why it should change those
options.

I'm not that bothered - if it's decided this is in the best interests of
bogofilter I'll change my scripts and won't lose any sleep over it.
