The thing is: in a checkout, the flow of data is HEAD -> index -> worktree To check in, the flow is exactly opposite. There are also legal workflows where you do not work on the worktree at all. And there are legal workflows where you work with multiple indices/worktrees. Now, it appears pretty obvious to me that the logical thing is to tell the (current) index what is supposed to be checked out and what not. After all, a merge is done inside the index. And if the merge touches parts outside of the sparse checkout, it is natural to have the index know about it. Because the merge _has_ to complain then. In any case, isn't it clearly the more elegant solution to just put the information into the index when you touch it _anyway_? I am really puzzled why people think it is a good idea to separate the file metadata from the information what files were checked out to begin with, as if they were totally independent. Because they are not. Ciao, Dscho
