Why do you ignore this possibility, and merge stuff that will break it? Do you have an alternative solution to the problem of green addresses spamming the blockchain? As I noted in the pull request, stripping extra data has no negative impact on normal transactions, and clients creating these can be written to expect the txnid to change (or simply not care what the txnid is).
