This would be a problem if it was used in the merkle tree, but I'm pretty sure
using it for input selection would be pretty safe. One could even avoid the
index by simply using the hashScript as the sole input value; then even
CoinJoins would be safe without breaking chains of transactions (although this
would break address reuse entirely - but I don't see that as a problem in a
theoretical world). One of those things that an altcoin could improve upon
Bitcoin with... ;)
