Oh good, I was worried this would mess up the feature flags for bevy_ecs. Nice to see this work cleanly.

I think this makes sense there: it's a tool to work with type names.

Can you update your migration guide to be a bit more descriptive? It doesn't actually describe the fix when read outside of the context of this PR.

Given that use_shortnames for schedules needed to be feature flagged behind bevy reflect, I'm not sure that this is a clean change. That feature is about using shortnames when reporting ambiguities and has nothing to do with bevy reflect.

I think I see what you mean now. What do you suggest as a solution, keeping in mind we, ideally, don't want a utils crate.

I think the only real options are to move it into it's own crate in the bevy repo or move it out like we did with atomicow.
