if you change this to exponential, you enable the retry policy feature.

Why not exposing these two as well?

we'll expose when we'd need them

we'll need them for the e2e if you want the test to complete quickly :) https://github.com/restatedev/sdk-rust/blob/main/test-services/src/failing.rs#L122
Also I think in particular max_interval is important, otherwise the retry delay with exponent 2 quickly evolves into some too long delay!

Perhaps to avoid any confusion is better to rename this to sys_run_exit_failure_terminal

FYI this is the docs text I used in the other SDKs: https://github.com/restatedev/sdk-java/pull/375/files#diff-c7114c260c8e7e1653409b43f92d24cfd46e51517bf2ed166871dc963de54ff0R16

Why not rethrowing (as you were doing before essentially)?
