Modular LPDDR Memory Becomes A Reality: Samsung Introduces LPCAMM Memory Modules [1], fixes most of the problem. The only thing that soldered LPDDR ram offers is saved motherboard space. Which really isn't as much of a problem in modern laptop when SoC and GPU are so well integrated.
"Samsung says that LPDDR5X LPCAMMs only occupy 40% of the space of a DDR5 SO-DIMM, and improve power efficiency by up to 70%, roughly in line with the general benefit of LPDDR5X over DDR5."
