What, make a socket matching the M.2, that M.2s would be incompatible with?

  Intel actually does just that with wifi cards (CNVio/2 cards only work with specific chipsets and don't use PCIe/USB, while using the same keying as normal wifi cards).

    An M.2 2230 slot should be able to take Wi-Fi or NVMe since they're both PCIe devices. In practice there aren't many 2230 SSDs.

      CNVi isn't PCIe; non-CNVi platforms can't take CNVi Wi-Fi cards. > CNVi or CNVio ("Connectivity Integration", Intel Integrated Connectivity I/O interface) is a proprietary connectivity interface by Intel for Wi-Fi and Bluetooth radios to lower costs and simplify their wireless modules. In CNVi, the network adapter's large and usually expensive functional blocks (MAC components, memory, processor and associated logic/firmware) are moved inside the CPU and chipset (Platform Controller Hub). Only the signal processor, analog and Radio frequency (RF) functions are left on an external upgradeable CRF (Companion RF) module which, as of 2019 comes in M.2 form factor (M.2 2230 and 1216 Soldered Down). Therefore, CNVi requires chipset and Intel CPU support. Otherwise the Wi-Fi + Bluetooth module has to be the traditional M.2 PCIe form factor. https://en.wikipedia.org/wiki/CNVi https://en.wikipedia.org/wiki/CNVi

        True; I was thinking of normal Wi-Fi cards.
