# Objective
- Make bevy_app's optional bevy_reflect dependency actually optional
- Because bevy_ecs has a default dependency on bevy_reflect, bevy_app includes bevy_reflect transitively even with default-features=false, despite the optional dependency indicating that it was intended to be able to leave out bevy_reflect.
## Solution
- Make bevy_app not enable bevy_ecs's default features, and then use [the `dep:` syntax](https://doc.rust-lang.org/cargo/reference/features.html#optional-dependencies) introduced in 1.60 to make the default bevy_reflect feature enable bevy_ecs's bevy_reflect feature/dependency.
---
## Changelog
- bevy_app no longer enables bevy_ecs's `bevy_reflect` feature when included without its own `bevy_reflect` feature (which is on by default).
