One other point I don't think was made - as I recall, the extra months added to 24 or 36 month certificates are intended to be a buffer in case the customer is late in renewing. Even though we start reminding customers that their certificates will expire before the end of 24 or 36 months, a surprising number of customers can be slow in completing all the renewal steps, especially for OV and EV renewals.

If that had happened, I'm sure a good CA would have warned their customers of the upcoming change in certificate "style" and provided them with whatever test certificates they needed. One does not have to wait until certificate renewal is due in order to conduct this sort of testing.

Sure. But if it's identical apart from dates (often) or dates and key, does it really need a month of testing?
Again, if it's not possible to deploy a new cert faster than that, something is broken somewhere, and it's not the certificate's lifetime.
