There have been bugs in the past with regards to symbols being pulled in
without the actual import being there (due to stuff that was imported using
it IIRC). I don't know what the current state of that is, but I recall there
being a deprecation message about that behavior going away. So, if that
behavior finally went away, then code could have compiled with the previous
release but not the new one.
