We'd prefer people use them but recognize that the current community
of users of encrypted electronic mail don't. There must be a reason.
Actually, there are two reasons:
(1) They can't get them, or don't know how (Apple's PowerTalk was the
first mass-market way of getting a certificate that I know of).
They want to send signed and/or encrypted email anyway.
(2) Sometimes people want as much anonymity as possible. A bare key is
the minimum information necessary for an encrypted non-real-time channel
in the absence of prior arrangement.
