Another way is to use git-worktree, which would solve the gc issues mentioned below? I view alternates as a historic artefact as the deduping of objects client side can be done using worktrees, and on the serverside - I think - most of the git hosters use namespaces and put a fork network into the same repository and use pack islands. Can you elaborate on why worktrees would not solve the problem? (I initially was hesitant to use them as I liked going into .git and tempering with files such as the config directly. But now I cannot `cd .git` any more; it turns out the advantages outweigh this corner case that I was attached to)
