Remember: some years ago "off by one" was treated as useless for
exploits.
Any type of data/file hiding (of course, alternate data streams in
the first place) can become the last brick required for some new attack
vector.
So, while currently I can't present any workable scenario, I
wouldn't consider such type of data hiding as "not a security-relate
problem".
