Knowing that an update would invalidate an extension would in no way
prevent you from installing the update if you chose to do so.  But not
knowing that one's extension will no longer work until after
installation causes some people to delay installation for longer than
necessary, until they know for certain via external sources that there
is an extension that will work.  I tend to prefer information.  YMMV.
