Me too! This is an awesome hack.

There is an important caveats: You must make sure you never ever create
a commit tx which is identical a previous one.

There's also a requirement that you store all previous signatures,
avoided by both the original draft scheme (using BIP32 and handing over
old private keys) and the deployable lightning chain-of-hashes.

Since these scripts will hardly ever hit the chain, I think this a
premature optimization. But maybe I'm still a bit stunned by this use
of OP_CODESEPARATOR :)

Great work!
Rusty.
