Bevy contains a bevy_reflect::impls::glam module which contains a bunch of impls for Reflect and related types, let's take Vec3 and its impl as an example:
Vec3 Reflect impl all mentioned json is inside the bevy_reflect.json file

},But the actual module these impls come from, has no items inside it at all:
"0:1211:1777": {
"id": "0:1211:1777",
"crate_id": 0,
"name": "glam",
"span": {
"filename": "crates/bevy_reflect/src/impls/glam.rs",

1,

"#[cfg(feature = \"glam\")]"
],
"deprecation": null,

"module": {

}
}
Expected behaviour:
I would have expected the impls to be mentioned in BOTH the module items and the trait impls
