This may be excessive, but now that the topic has been opened, I'll throw
in what must be considerably less than two cents' worth.
The meaning of the flag in practice is, "I, the undersigned issuer,
hereby authorize the acceptance of certificates conveying the specified
privilege when signed by the subject of this certificate." The language
I'm hearing suggests that people may be forgetting this: that these
are instructions to the validator, not prohibitions on subordinate issuers,
who can do what they want. Bill's point about truth in advertising is
perfectly valid, but from that point of view I am entirely satisfied that
the system does not facilitate what it cannot prevent.
The granting of a privilege is one thing; the granting of the authority
to grant it is another, hence my suggestion that one may be a special
case. I would like to be able to say that I trust A to grant a
privilege only to appropriate people without feeling compelled to say
that I trust him with the greater responsibility of granting authority
to grant it. So I think that one is as different from zero as from infinity,
but two is not different enough from either as to warrant consideration.
Then, Don's point is perfectly good too: better to have and not need, etc.
I'm sorry if I'm not really helping a decision, there were just those
things I wanted considered, though I've probably said them before.
