Just sayin' I'd have gotten a set, but for general Dvorak incompatibility.
Sadly not enough users for Dvorak and ISO, since it's different profile SP charges it as a separate keycap, if you can find enough people wanting sure I don't mid putting this in

ISO is a little better since its R1 so it can be used as a esc key, while a Dvorak i believe is a R2 key right?
