Transaction replay blanket ban is wrong - needed for keyless contract deployment

I agree with you.

Though the point I was trying to make is that there could updated versions of the Deterministic Deployment Proxy (e.g. one that I’ve made) - the old one from 4y ago by you / Nick shouldn’t have to be the only one that ever exists.

For general purpose contract deployment, the deployer’s address should be included to prevent front-running by others, so I’ve made an updated version which I’ve described in Updated MicahZoltu's / Arachnid's Deterministic Deployment Proxy
