Hmph, I am not necessarily sure about "need to duplicate" [*1*], but
I do agree with the patch text---the bit should not belong to a
single "files-backend" backend.
[Footnote]
*1* obviously, a better alternative, if possible, would be to let
the more generic layer do so without forcing the backends to
duplicate. But even if such a change were possible and we
decide to avoid duplication, it does not make sense to have this
bit specifically defined for the files-backend and nobody else.
