You misunderstand. I'm talking about intending to run `git clean -xffd` under `~/src/some-project` (a git repo for some code) but accidentally running it under some other directory, such that it ends up running against `~`
Making aliases for working with `~`'s repo doesn't prevent that.
Yes it does. I do the same, with an alias and have .git somewhere else not directly in $HOME, but pointing to it with --git-dir. If you run git in ~, it will not recognize it as a git repository or worktree. You can only modify the repo with the alias or by specifying --git-dir explicitly.
These setup also prevents zsh/bash git prompt extensions from detecting git the the home folder repo, which can be confusing, I think.
