It is a concern if someone wants to add a short option that's compatible 
with that feature. Right now coreutils already has multiple long options 
(status and strict) that start with s, and another option which is very 
close (quiet) that also doesn't have a short option (and isn't 
implemented in busybox because why not; busybox doesn't seem to have a 
strict option either). Meanwhile on the bsd side there are other options 
which may also be useful including one which uses the same short option
letter. It's not at all unheard of to get requests to implement those, 
and implementing this in coreutils precludes that possiblity.
