Thanks, "95", that really makes me feel much better about BA not even bothering to send a notification e-mail. They can do it, pointlessly and randomly about "Preparing for your flight" and explaining to SCH's how to get to the bleeding airport. But telling you about a significant airframe/seating change? No way

Anyway, we're now 10G/J outbound, 10B/D inbound. We can live without holding hands for 7+ hours. Young mikey2124 advised us about that seating option, and at least we'll get (a) early service and (b) fast disembarkation.
