Curious.  It appears nobody has responded to this.  And the
regulars are usually so quick, too.  :-)

What _should_ happen is the same as what happens for any other
DNS record.  Anybody who caches it should do so only until the
assigned TTL runs out.  What _does_ happen depends on how it's
coded.  Hopefully it's not as bad as some of the web browsers
we've run into that won't notice a change without being restarted
first.
