Indeed - at least if you want to use all those variants for encrypted
mail. But usually people don't make up which variant of your gmail
address to use. You decide that by publishing it or mailing from it.

And that's also how PGP works, that is what I tried to explain in my
possibly too long mail. You decide which of your addresses to add
as User ID to your public key. And those are the addresses people
should use to send you encrypted mail.

Therefore I see no need for the openpgpkey specification to deal with
address variations. That does not prevent anybody from inventing a
webfinger standard to canonicalize email addresses, which could be an
additional, usefull service. But from a PGP key lookup mechanism I
expect to get keys which have the email I am searching for as User ID. So
if you really want to use 500.000 variations of your address, it's
PGP that has the scaling problem. Try to sign such a key ;)

Greetings,
Florian
