Well, as said earlier on, most likely we would have to operate under a harder constraint of only the physical keys with secondary print on the existing qwertZ layout can have have secondary print, and in yellow, without the requirement of changing det underlying keytops. But if we can persuade them to change that too, it would obviously leave us more options. But it would add extra expenses to have to produce two types of base keys, so we would have to argue harder.
