In #5845, I had added a method to update the world safely: Maybe you could add it? There were some discussion around it, you can find them there: https://github.com/bevyengine/bevy/pull/5845/files |

Might benefit from explaining why you'd want to use it.

It's the only way of safely getting a &mut World from an EntityMut without consuming self. Which sort of speaks for itself?
I'm not sure what to add to the docs that could make that clearer (Aside from being very pedantic) :)

You could discuss update_location here, but that's very gory-internals, and likely to go out of date in dangerous ways. If people care, they can read the code.

I was thinking: someone reading the doc doesn't necessarily see the source code. If they encounter this method, they may ask themselves why its here. But I agree with alice, it's really a minor thing and really depends on internals.

C-Usability
`EntityMut::remove_children` does not call `self.update_location()` which is unsound. Verified by adding the following assertion, which fails when running the tests. ```rust let before = self.location(); self.update_location(); assert_eq!(before, self.location()); ``` I also removed incorrect messages like "parent entity is not modified" and the unhelpful "Inserting a bundle in the children entities may change the parent entity's location if they were of the same archetype" which might lead people to think that's the *only* thing that can change the entity's location.
