## About The Pull Request

Simple rotation components number in the 8-9k range per round, and each
contains a needless callback datum as well.

These do not need to hold any state and can be bespoke elements, and the
proc to do things post_rotation can just be a normal atom proc.

flag requirements like the wrench</summary>

## Why It's Good For The Game

Makes a heavily used element much more lightweight, saves a few mb of
memory.
