After starting learning about etckeeper after my last question merge two files with nvim -d or vimdiff I wondered the following:
The approach with a staging worktree explained by https://stackoverflow.com/users/23118/hlovdal sounded reasonable. Reading the etckeeper tutorial it seems they also follow the idea of a staging area but describe it with clone instead of worktree.
The only reason which makes sense for me, that other VCS do not have the capability of worktrees like git has and they decided to explain an approach with a more common tool/command?
Am I right with hypothesis or are there reasons they used clone instead of worktree?
