Well seat selection is just working out you can charge for something that some care about (will pay for) and others don't (won't, largely unharmed). But luggag

Well seat selection is just working out you can charge for something that some care about (will pay for) and others don't (won't, largely unharmed). But luggage for example: having it was to some extent subsidised by people who didn't/you paid for it whether you wanted it or not, in the bundled price. It's more a problem of advertising & comparison IMO, I don't mind (quite like) these things being separated out otherwise.
