You think order-of-creation has something to recommend it? I don't see
what. It just makes it extremely painful to control the firing order
when you need to --- you end up dropping and recreating all the
triggers, which is a tedious and error-prone approach.

You can equally easily run into similar problems with creation-order
firing as well. There's no substitute for actually thinking about the
interactions of multiple triggers on the same event...
