<!-- Thank you for creating a tracking issue! 📜 Tracking issues are for tracking a feature from implementation to stabilisation. Make sure to include the relevant RFC for the feature if it has one. Otherwise provide a short summary of the feature and link any relevant PRs or issues, and remove any sections that are not relevant to the feature. Remember to add team labels to the tracking issue. For a language team feature, this would e.g., be `T-lang`. Such a feature should also be labeled with e.g., `F-my_feature`. This label is used to associate issues (e.g., bugs and design questions) to the feature. --> #68705 adds a method in LinkedList to remove an element at a specified index. The feature gate for the issue is `#![feature(linked_list_remove)]`.
