THIS PULL IS STILL INCOMPLETE, I JUST CREATED IT TO MORE EASILY DISCUSS IF THE WORK SHOULD BE FINISHED

Objective

• Describe the objective or issue this PR addresses.
• If you're fixing a specific issue, say "Fixes #X".

Solution

• Describe the solution used to achieve the objective above.

---

Changelog

This section is optional. If this was a trivial fix, or has no externally-visible impact, you can delete this section.

• What changed as a result of this PR?
• If applicable, organize changes under "Added", "Changed", or "Fixed" sub-headings
• Stick to one or two sentences. If more detail is needed for a particular change, consider adding it to the "Solution" section
  • If you can't summarize the work, your change may be unreasonably large / unrelated. Consider splitting your PR to make it easier to review and merge!

Migration Guide

This section is optional. If there are no breaking changes, you can delete this section.

• If this PR is a breaking change (relative to the last release of Bevy), describe how a user might need to migrate their code to support these changes
• Simply adding new functionality is not a breaking change.
• Fixing behavior that was definitely a bug, rather than a questionable design choice is not a breaking change.
