If you're a manufacture, what incentives LPCAMM2 gives you over soldering the RAM? With soldering, you can upsell the upgrades and force ppl to replace the whole machine every 1-2 years. How does LPCAMM2 benefits the company? I'm talking in general, not some niche manufacturers like Framework.
TBH, I don't think many will adopt this. Maybe it will show up in some expensive laptops like high end gaming and workstation, but majority of them wouldn't.
