# Objective - Continue work of #2398 and friends. - Make `.system()` optional in run criteria APIs. ## Solution - Slight change to `RunCriteriaDescriptorCoercion` signature and implementors. - Implement `IntoRunCriteria` for `IntoSystem` rather than `System`. - Remove some usages of `.system()` with run criteria in tests of `stage.rs`, to verify the implementation. |
