Notice how the complexity of this grows suddenly when you start thinking about infrastructure failure and restarts due to deployments. I have seen this play out dozens of time in my professional career where these systems although starts very simple but eventually becomes a huge maintenance burden over time. This is where high level abstractions like Durable Execution is much more powerful for developers which has the potential to abstract out this level of details. Basically code up your application like infrastructure failures does not exist and let underlying Durable Execution platform like Temporal or something similar handle resiliency for you.
