I'm fully aware of that; I just didn't think it all the way through. Ergo ... an exchange would constitute a new sale (and the exchanger could be any ol' body), so they'd instead have to update the existing fire-control module and send it back to you. But then let's think the rest through ...

Assuming all that's true, a simple date range isn't gonna work. These updates could go on for many months (probably years, like Takata airbags), so, as I wrote originally, they'll need a way for us to check individual serial numbers, because, with basic safety at issue, used items are just as important as new ones.

Maybe they'll tell us this stuff Monday.
