I wasn't really too worried about picking apart the approach. If order mattered, you'd be looking at other approaches anyway.

Mainly just calling out a gotcha where you might quietly miss out on scheduled events with no warning.

For example:

1. Object written to successfully to bucket.

2. `s3:ObjectCreated:Put` is _never_ delivered.

The possibility of duplicate events are warned about a lot in the AWS ecosystem, and this sets up an expectation of "at-least-once" delivery.
