`git clone --local` does hardlinks, space usage is quite low, so I'm not really sure that part holds up. Maybe in Windows? Switching branches can definitely be slow tho, yeah. Do worktrees change that somehow tho?

From all I've read so far (quite limited!) they just sound like replacements for `git stash` or making a temporary commit / branch, but with a new set of commands and rules to learn. I don't find `git commit -am tmp` (literally, I just do that) to be particularly worth optimizing further, and worktrees so far sound like substantially more work.

edit: ah, yeah, updating multiple clones is definitely annoying / easy to forget, totally agreed there. that alone might make it worthwhile. I only need it like once a year so I probably won't, but I do know some coworkers who do it a lot.
