That's totally feasible, and works for small to medium traffic (SQS scales seamlessly from 1 message per year to millions per second).

In practice, I've never seen this implemented correctly in the wild- most people don't seem to care enough to handle the transactions properly. Additionally, if you want additional features like DLQs or metrics on stuck message age, you'll end up with a lot more complexity just to get parity with a standard queue system.

A common library could help with this though.
