It has been running for us on certain routes for the last 6 months or so. One way upgrade on the more expensive Club route deal tickets. Nothing at all to do with the public offers. Pretty sure there was mention of this in the last Investor presentation too - seen as a revenue maximisation and loyalty tool for certain customers. We have good fares from VS on the table hence BA's interest in offering this.
Other airlines have run similar deals for us in the past, most memorably CX on both sectors.
