Yes, this is true, I'm mostly worried about the elliptic curve signature part, as everything else could be fixed with an emergency hard fork (except SHA256).
Sadly OP_CAT operation is disabled (or substring equality operation), which would make lamport signatures available again for high value transactions. I would love it if lamport signatures would be enabled again (it would be quite easy to do), but I'm afraid that there isn't enough concensus to do it at this point, because some people would think that it's wasteful, and also lamport signatures are dangerous, as they can be used only once.
