I had hand pain and bought a Planck EZ for ergonomics but resold it almost instantly because of the issues you note. It’s small so your wrists are angled and your hands are bunched together more than even on a standard keyboard. I discovered that what I really needed was a split sculpted keyboard instead and the ortholinear aspect was not a panacea. Yes my fingers would more easily move in a line than side to side, but my wrist and arms were so far from being straight it was actually worse.
