How about mounting your dotfiles directory (~/.config) or even your entire home directory on the remote system using SSHFS or NFS? I'm sure somebody would have tried it or some project may already exist. Any idea why that isn't as prevalent as copying your dotfiles over?
I’m trying to imagine why sshfs mounting the less-capable remote onto the workstation would be blocked.
That requires the remote machine to be configured to SSH into your local machine. In the scenario where OP's project is useful (SSH to foreign machines) I might not want that.
On the other hand, if the remote machine is mine, it will have my config anyway.
