Follow-up: I reckon a detect_cyclic_traversal debug feature could be nice. Internally just keep an EntityHashSet and panic! when a cycle is detected.

Agreed. There's a ton of methods that could use this.

…tyCommands` (bevyengine#17463) # Objective While being able to quickly add / remove components down a tree is broadly useful (material changing!), it's particularly necessary when combined with the newly added bevyengine#13120. ## Solution Write four methods: covering both adding and removal on both `EntityWorldMut` and `EntityCommands`. These methods are generic over the `RelationshipTarget`, thanks to the freshly merged relations 🎉 ## Testing I've added a simple unit test for these methods. --------- Co-authored-by: Zachary Harrold <[email protected]>
