I dont' know about other impls, but Blink/Webkit generally just
reparses the entire stylesheet after *any* change.  I dunno what
optimizations may exist there, but I know we're generally pretty
pessimistic and just blow things away and reparse, because it's
simpler that way.  So having to do that for a @namespace change isn't
a big deal for us either.
