This, and in terms of repairability/sustainability, it's hard to make an "everything device" and do it well. Every time you think you got all user requirements covered, another user comes around the corner with a new set of hyper-specific requirements, and you're back at square one figuring out supply chains and design fundamentals. If your aim is to make something repairable and sustainable that is hard to make that way, it's much more feasible to just make two separate devices.
