Gerv, I'm trying to understand your points.
The only certs in discussion are pre-BR certs (which by definition are not covered by the BRs). They are expiring by their terms (validity period) every day, and no one has proposed extending their validity period. Can you provide an example of "an extension of my argument," some action by a CA that is rekeying an existing BR, that could lead to serious problems? What kind of pre-BR cert, if rekeyed (reissued) by the CA for the same expiration date, will cause some new problem? I can't think of any.
So far as I know, the only "issue" in rekeying a pre-BR cert is whether or not the subscriber should be revetted - isn't the correct? (For example, if the pre-BR cert is a 10 year cert issued several years ago.) Is anyone else arguing that some other part of the BRs is so important it must be applied to any reissued / rekeyed pre-BR cert? What?
It seems we are wasting a lot of time and cycles on this, when the problem/situation is going away on its own.

Indeed not. But Ryan's point is that the arguments being deployed here could be used to support such action for exactly the same reasons. If the BRs don't apply to reissues, as some are arguing, then they don't apply full stop. And if someone comes along later and wants to make them not apply to some other aspect of a reissue, one can hardly object.

The question of whether there is a risk for this particular change is a separate question to whether the BRs are intended to apply to reissues or not.
One possible outcome is that we clarify that the BRs apply to reissues entirely, but that we carve out an exception for certificate duration (or some other aspect) because we think that the risk of varying that particular aspect of certificates is not great.

I think that people are less concerned about that, and more concerned about the grave danger if your line of argument is accepted - because it proves too much.
