It might be worth pointing out that changing the names of items, objects and blocks, as well as removing said articles, can have world-corrupting effects such as crashes, items turning into PGI's, and leaving object collision geometries where objects once were.

EDIT: No, I'm wrong. The files were moved. That has the same problem. Except in this case, it's worse. Because now I have to introduce a local patch to my local mod mix that changes the name of the moved file while adding the original version back so my main base world isn't destroyed.
