I'm not saying you can code it so that it will behave flawlessly...  
obviously you can't do that without prior knowledge of the upcoming  
changes.  But you can code it so that when it fails, it fails in a  
way that doesn't expose private information.

For example:

if ( in_array($status, array('publish', 'attachment') ) {
	do_foo();
}

Instead of:

if ( $status !== 'draft' && $status !== 'future' ) {
	do_foo();
}

If you do it the first way, you'll never be surprised by what is  
caught in your net, only by what isn't caught, which I think is a  
preferable error.
