A couple of minutes ago, I renamed a trait, and all uses of it, across a handful of files, using a simple sequence of: SPC c r Alt Backspace Roleplay RET. It updated the trait name, and all uses of it across all files where it was used.
No tokens were burned, and the entire operation took less than a second after pressing RET, because Emacs & LSP are so much better than LLMs for this purpose in every concievable way, except rent seeking.
