I certainly support this point of view.  However, the scope of the
required changes isn't immediately clear to me.  We might potentially
need to patch every single fsck program; e2fsck is sort-of patchable
but Ted wasn't happy with the idea.  And worse, we have to deal with
btrfs, which currently isn't fsckable if mounted *at all*, let alone
read-only /.  While I live in the hope that one day btrfs will be
sane, I won't be holding my breath.
