It shouldn't come to that. Where did Grandma get her mailto:-based
WebID? Can we discourage the provider from this practice without
saying "it's not WebID"? Can we write the spec in a way that
discourages people from pushing out such things to non-technical users
before there are enough consumers?

conservative in what you send; be liberal in what you accept."

publishers/providers SHOULD [your words here] ...?
