Very unlikely. Apple can argue that less than 1% of computers users ever upgrade their memory (which is true), and after all, did the EU intervene when GPUs dropped their slotted memory?

The difference there is that slotted GPU memory is demonstrably impactical, but the memory on the M4 isn't demonstrably better than the LPCAMM2 module above. It's literally the exact same spec. Not that I expect the EU to do anything either when they didn't act on Apples soldered-in SSDs, which definitely aren't any better than standardized M.2 drives.

Actually, incorrect. On some scenarios, you’d need up to 4 CAMM2 slots to do what Apple does. This is due to CAMM2 maxing out at 128 bit busses; but M3 Max chips are currently at 512. Needless to say, battery life most affected.

Yes, the higher end Max and Ultra chips would still need soldered memory. Two CAMM modules flanking opposite sides of the SOC is probably doable though, so I think the M Pros could practically have socketed memory.

GPU memory is 20 MT/s+, Apple is ~6 MT/s, LPCAMM supports ~7500 MT/s.

Easy heuristic: if your memory transfer rate is more than 1.5x the standard, you can solder RAM. If not, you must use the standard.
