> messes up the height for packing the keyboard away

You design things for how they are used. If it is a keyboard meant to live out it's life on desk, then why design for how it is packed away? Perhaps if it was advertised as a portable travel keyboard then designing for storage would make sense.

I think you are misunderstanding their use of the word ergonomic. They're using it in the literal sense, not the colloquial sense of gimmicky layout keyboards. All keyboards should be ergonomic in the literal sense.

I'm arguing the market already has a number of minimalist standard layout keyboards (the Nuphy lineup, even major brands like Logitech). Making something ergonomic and portable would be an interesting differentiator. The Atreus ( https://shop.keyboard.io/products/keyboardio-atreus ) is a nice example but gets a bit too minimal whatwith not having a number row.
