This curse extends to mechanical keyboards as well. There exists all sorts of fancy, beautiful and odd keycap sets... for Americans. Some times for German and French. If I get really lucky, I'll find some with a "Nordic" layout, which is an abomination that combines dk/se/no.
And I thank god every day we don't. The ISO keyboard is awful. Left shift is too important of a key to be 1u. I don't need a massive enter key that lives on two rows. Just insane choices.
I use a Dvorak-based layout on Qwerty keyboards, so in normal usage they could as well have blank keycaps.
Despite that, the Qwerty keycaps remain useful for me, because my keyboards are not programmable, so the key mapping is done by the operating system. When I have to unlock the computer with a password, after booting, the keyboard still works as Qwerty and the keycaps help me in entering the password, because nowadays I touch-type only on Dvorak, while on Qwerty I must return to hunt-and-peck, as there are many years since I stopped using Qwerty.
So only because of this password entering, I prefer to not have blank keycaps, even if I ignore them in normal usage.
