Yeah, when I used to work on the Shuttle program, we had to paint all the
stainless steel piping on the pad with a special aluminized paint to
protect against the HCl formed from the SRB exhaust.

And yet, still probably better for the atmosphere than lighting a tire on
fire with laughing gas.
Also, don't forget that the chlorine in AP mostly ends up as hydrochloric
acid (HCl), so the exhaust plumes of most non-trivial solids are acidic.
(And if they're still burning at high altitude, the chlorine content is
bad for the ozone layer too. Not an issue for burns lower down, because
HCl is so reactive and so soluble in water that little or none makes it up
into the stratosphere. Just as well, since volcanos put out a lot of it.)
