Steve,
The phrase "since it's clear" was used in your message without
qualifiers, surely a typo ;-). There are differences of opinion about
the proper form of ID for use in certificates and the need for a
certification infrastructure than is more than the electronic
equivalent of "friend's and family." Views counter to the ones you
cite as "clear" have been well-articulated (at least as well and
sometimes beter than many of the countervailing views). Thus, what
may be clear to you may be murky to many of us.
Steve
