We must fix X.509 since it is not broken.

I am not suggesting that we should fix X.509, I am pointing out, in my
own roundabout way, that X.509 certs are supposed to have a canonical
form. But it seems they do not.

Makes me wonder why we go to all the effort of using a supposedly
canonical encoding that isn't? If we can only rely on the original bits
in the cert when checking the signature, why bother?
