... which would be an indication that the behaviour is most likely

... and indeed it is useful in some rare cases.  Either

    git diff <tree-ish> <pathspec> | git apply -R

or

    git checkout <tree-ish> <pathspec> &&
    git reset <pathspec>

are what I would use, and as an old-timer, the former is what I do.
