You are missing my point: What good are the keys if the ones you are
handing me are to a Waffle House or 7-11?

I was basing this comment on my previous comment that "I sign some
mail" is pointless. So if it is pointless, you now have a binary
choice. I sign all mail or I don't. If you don't, no need to publish a
record. Which as logic would have it, would mean that if you did have
a record, you sign all mail.
