The implementation is good, but now it makes me wonder why we use ShouldRun instead of bool in the first place. If the intention was to eventually extend it, this will break the impl if that ever happens.

@IceSentry ShouldRun already has more variants than just Yes and No, if that was what you meant.

Run-criteria are kinda cursed. They have the ability to rerun themselves and the systems they control.
It's how fixed timestep is currently implemented: https://github.com/bevyengine/bevy/blob/main/crates/bevy_time/src/fixed_timestep.rs#L151-L174.

I doubt we will extend ShouldRun in a way that converting from a bool stops making sense,,
and I hope we can yeet the current impl and replace it with the relevant parts of stageless before 0.9.

Oh, you're right, sorry, it was a bit too early in the morning for me to do a review 😅

This is a good stopgap. I intend to remove the ShouldRun type completely in favor of a bool by 0.9, but that's easy to do regardless.
