I can't remember which manufacturer it was (iirc it was either Dell or HP), but I recall a couple of engineers from that manufacturer being on a podcast saying that their DOA RMA rates dropped dramatically after switching to soldered RAM.

One compromise I've seen in laptops is to have both soldered ram and a SODIMM socket. Stock config comes with soldered ram giving the end user the ability to add more ram as required.

CAMM2 modules could / _should_ help in returning replaceable modules to laptops and keep the benefits of having the ram mounted closer to the cpu, but at the cost that its (atleast atm) only a single module, so if you were upgrading from (for example) 8gb to 16gb, you would be left with a unused 8gb module and try and sell it on the resale market.

it would take 4 CAMM modules to have enough memory bandwidth to match M1 Max

where are you going to put them in an appropriately thin chassis?
