> We know that we can ignore it because it's just FATE doing the right thing -- we wanted
to delete a table, but it's already deleted, so there's nothing to do. Super.
> The issue is that a less-experienced user might not realize that they can ignore this
message. I think that in the DeleteTable FATE op, it would make sense to fail quietly when
we try to delete something that is already gone. Yes, it is still deserving of an INFO or
DEBUG message, but I don't think this should propagate up to the monitor.
