Thanks, that's correct. I think the only thing left is to add a verifier
pass, which everybody seems to be agreed is nice to have. The plan is to
add it only to master without back-patching. I assume Thomas did not
have time for that yet, so I've added the latest suggestions into his
patch, and going to open a CF item to not forget about it.
