OK. So leaving aside DV for the moment, it seems clear that any
proposals to reduce issuance lifetimes short of a MUST are not going to
have any significant effect. This has been RECOMMENDED since the EV
standard was first written, and less than one in five EV certificates
follows that recommendation.
This is perfectly understandable, given market forces, but I hope it
will help some CAs understand why browsers feel that a mandatory maximum
is required rather than anything softer.
