Yep. Because IF EXISTS is in a lot of object destruction commands,
adding a modified tag seems very confusing, because in fact the DROP
TABLE did succeed, so to give any other tag seems incorrect.
I think the only option would be to use INFO instead of NOTICE, but
because the output is optional based on whether the object exists, you
might say NOTICE is the right level.
I am afraid we might just need to live with the current behavior.
