I had to call LX for an unrelated reason today and asked it out of curiosity. The agent said that I'd be able to book an extra seat for the adult "regardless of weight" and added that this would be honored "as strictly as any other seat", but that "overbooking could mean adjustments, as with any other reservation".

Given how many European fares have very low base fares and very high YQ, I'd be surprised if this actually works in practice. If it does, people have been really quiet about it.
This is what I think as well, hence my post and my question about missing anything obvious.
