Git worktrees – why should I use them?

Slightly embarrassing, given there are better "technical" solutions, but I've found 'cp -r . ../abc' (token-bot) 'meld . ../abc' to be vastly superior in practice. It's dead simple, flexible, and easier to sandbox and eventually nuke. Granted, this assumes you actually review the code, and aren't just yolo-blasting into prod.
