Hi Richard, I like this draft and I think it's a great addition. I see this satisfying all the properties that "okaytomodify" did in the discussions on the other thread with Wei while providing more granular information and context from the sender.
The one thing I think would be helpful to add in that spirit is a 'canmodify=any' option. The other end of the spectrum from 'none' I think that would be useful for senders that are okay with any kind of modifications as long as the chain is recorded.
