It seems likely that the 'module' would just cover the entire space of the board as-is if they did this with a modern intel system anyways, especially when there's also SODIMM module slots, an m.2 slot, and 4 full tb4 ports on the board. All those high speed bus interfaces are probably tied directly into the CPU, the chipset, or both, and so are largely gonna be covered by any confidentiality agreement intel imposes on vendors of those parts. The Pi4 CM is a much more modest device by comparison. It has no ram expansion and only a few lanes of PCIe, USB3, and some other fairly standard IO interfaces otherwise. Realistically, the frame.work mainboard is the compute module. You plug it into the equivalent of a CM carrier board with the TB4 ports.
