I just don’t think most / any connectors are going to be compatible with modern ddr speeds. Even doing the layout on these smd pads takes a lot of work to make it right. You’d be taking a major speed downgrade which would limit your performance way more than this ram amount upgrade overcomes.

Quick Edit: storage is another beast entirely where I agree with you completely. Looks like steam deck you can upgrade the ssd and it’s at least way easier than this. Comparable to a laptop.
