I would love to be wrong but I dont think DIMM will be a thing on Mac any more. Not only does it not make economical sense for Apple with additional DDR5 memory controller support and testing, they can now also charge substantial premium for memory.

DIMMs likely won't be a thing anywhere before too long. They're too large and problematic to deal with for the latest memory interfaces (which previously had only been found on GPUs). There's only so much you can miniaturize before the connectors become a real problem - and we can now put an entire "computer" in a single package.

I'm interested to see when the PC form factor goes away completely, likely 1-2 generations of product from now.
