I think this last point is the main reason *for* setting include-revoked
to "on" by default.
Otherwise, if the keyservers supported the include-revoked=off option,
Bob could prevent anyone from finding Alice's actual key unless they
knew the configuration option.
Alice has key 0xDECAFBAD. she uploads it to the keyservers.
Bob creates a key, puts Alice's name on it, and uploads it to the
keyservers.
Bob uploads a faked (invalid) revocation certificate for 0xDECAFBAD.
Charlie searches for a key with Alice's name on it, and finds exactly
one: But it's Bob's key!
This seems like a bad arrangement. defaulting include-revoked to "on"
would make it so Charlie can see both keys.
