   This tightens up the IsStandard() rules so transactions that put extra data in their scriptSigs are considered non-standard.

   How about just stripping it out instead? ;)

   To elaborate, stripping it out would enable service providers to add an extra signature for 0-confirmation trust, rather than the blockchain-spamming “green addresses” proposal.

   Stripping is a bad idea, that changes the transaction id.

   It should have no effect on normal clients, which won’t add extra data. Clients that do add extra data can be written to expect the change.
