I can almost suck it up on a OW connection - it is a bit unfair that BA have to hand my luggage off to QR in Stockholm on a cheapie ex-EU - a station that BA wouldn't usually handle much connecting luggage in and I'm only doing in the interesting of money saving

But it is absolutely crazy that a BA to BA connection is not accommodated - there are no mainstream revenue abstraction opportunities that I can think of. It is just as much risk to them loosing the bag if I take it up and recheck or they move it for me. So I can fully imagine at least this part of the policy (maybe with AA/IB alongside) being redacted in the near future - we shall see!

Could make a nice revenue earner - that is how Scoot/Tiger do it in Singapore I understand - either book a through ticket or be liable to pay for the service if you want it on the day!
