The way we think about durable execution is that it is not just for long-running code, where you may want to suspend and later resume. In those cases, low-latency implementations would not matter, agreed.

But durable execution is immensely helpful for anything that has multiple steps that build on each other. Anytime your service interacts with multiple APIs, updates some state, keeps locks, or queues events. Payment processing, inventory, order processing, ledgers, token issuing, etc. Almost all backend logic that changes state ultimately benefits from a durable execution foundation. The database stores the business data, but there is so much implicit orchestration/coordination-related state - having a durable execution foundation makes all of this so much easier to reason about.

The question is then: Can we make the overhead low enough and the system lightweight enough such that it becomes attractive to use it for all those cases? That's what we are trying to build here.
