It's not the same basic thing. Given a SSL certificate signed by a
trusted authority, using SSL adds protection against DNS spoofing and
man-in-the-middle attacks. If otherwise identical http and https URLs
are considered the same identifier, that protection goes away,
regardless of which URL a user chooses to use or the protocol prefers.
Calling http and https URLs equal weakens the strength of the
assertions that OpenID is *able* to make.
