Not much redesign would be required tho, many laptops have hybrid memory like one slot of replaceable ram and soldered ram near it, so they could still keep things (soldered ram on chip) the way they are and just add in soc architecture interface for additional slots of replaceable ram, edit: but we all know that they wouldn’t do it unless they forced by EU
It lets you build one motherboard with all possible ram options.
The smallest one has all it ram soldered on. Therefore less time is required in assembling the laptops. All other patients just need the extra ram placed in the dimm slot.
Generally you can upgrade RAM of different capacities, but only the amount of RAM that matches the original will run in dual channel. I’ve done it in a couple of machines, and it worked fine. the extra RAM should take a small performance hit, but In my case the tradeoff was worth it. I’ve also upgraded RAM beyond the specified max. Hasn’t always worked.

I’ve never understood why so many manufacturers do that (laptops with 1 slot soldered and 1 slot replaceable) it seems like the worst of both worlds:
