The peripheral keys which were static in the old design was because we had to use an existing display. Making a custom E Ink display needs to be in at least 300k minimum order quantity and a $500k NRE so we had to wait until we had a mass production order; the current design has a new display which means all the keys are remappable. It wasn't lazy design, just a compromise we had to make until we had the capital.
