That has not been conclusively proven. However, even IF there is merit to that claim, CAMM/CAMM2 is NOT the way forward. CAMM/CAMM2 does NOT have the flexibility and configurability of standard DIMMs. It might be able serve mobile to reasonable effect, but not desktop/workstation/server applications. Especially not as designed. It's a concept that needs to be shit-canned because that's where it belongs, in the garbage.
Abused? Or used properly to proper effect? Narrow-minded moronic designs need to be called for what they are.

CUDIMM Standard Set to Make Desktop Memory a Bit Smarter and a Lot More Robust (anandtech.com).
Those are all JEDEC standards, nobody is going to get royalties for pushing those news connectors. If anything the industry as a whole would have an easier time to just give up and solder everything.
For DDR5, SO-Dimms are really behind DIMMs when it comes to speed. Even the sweet spot 6000Mhz CL30 doesn't exist in that format. The absolute majority of the sticks use JEDEC, with Kingston being the only brand selling a single SKU with timings a bit tighter. Even G-Skill of all brands is only selling JEDEC ripjaws. Buy a ROG, Alienware, Clevo, XMG, Puget laptop, the best that you'll get is 5600mhz, with loose timings. (unless you buy the 18" Alienware) In the DDR4 era, they were selling far more laptops with XMP memory.
Yes, abused in a discussion about laptops. Camm was developed to fix laptop problems...which it does. 4 dimms laptops are an insane rarity in 2024, and still cannot match the 256GB maximum allowed with camm2. And you know what else it solve? All those poor laptops being sold in a single-channel memory setup. The solution to have the so-DIMMs as PCB expansion might work for the laptops using a smaller battery, but what about the other? lots of laptops are 50% battery 50% PCB now. The other side of the PCB isn't empty either. What about the trace length? quality ? CAMM even managed to make LPDDR5 something not soldered anymore. Remember that most laptop makers have bad faith, to begin with: Asus Zephyrus laptops with Zen 5? still using good old soldered LPDDR5. The easy way out. That's the path that they will
always take. Unless someone else proposes an easy solution for them. (any connectors isn't btw, it's always going to be more expensive for them than soldering, LPDDRx camm2 being used is a favor)
JEDEC is the one who started to look at it for desktop use because they think that DDR7 and up might be troublesome. But as you can see, there are multiple solutions developed to fix that problem.
If JEDEC is full of shit about the future specification of memory, then how do we know that everything managed by them isn't also a web of lies ? I don't understand what they have to gain by doing this though.
