If the notices about implicit drops (triggers on tables, etc.) has been
found to be useful in both creation and destruction then I would assume
that this information would be wanted as well.
If the above information has not been found to be useful in the past,
then I would expect it to continue as chatter.
Personally, I find it to be chatter and turn off NOTICES in general, but
believe it to be consistent with similar messages in the past.
