I'm interested in your use cases here. While I agree that this is an
interesting feature, it also means that practically, a user who checks
out a file that's added this way may find that git status marks it as
perpetually modified until a properly cleaned version is committed.
Moreover, even "git reset --hard" won't fix this situation.
We see this problem extremely frequently with Git LFS where people
change the .gitattributes file but don't run "git add --renormalize ."
and then end up with this problem. However, it's not limited to Git LFS
in particular; anything that uses filters, working tree encodings, or
end of line attributes can be affected.
So I think that while this might be a useful escape hatch for users, I
definitely want to see a compelling rationale for it and a big warning
in the documentation and an update to the relevant entry in the Git FAQ
before we accept such a patch.
