While I agree with your general sentiment, the 10 key being on the "wrong" side could be good, perhaps, in some cases?

Historically I've done some heavy spreadsheet work where the resting position of my hands which minimizes movement is right hand on the mouse, left hand on the 10 keys. On a normal keyboard that has the disadvantage of causing a "closed" posture which isn't entirely comfortable.

Outside of that kind of niche use case though, it definitely feels like a strange choice for developers.
