For the removal of eMMC in favor of a M.2 NVMe PCIe SSD, you do realize that the RK3399 SoC has a built in eMMC interface?
Very little external logic needed. Yes, their is board space & connector required. But, tiny compared to choices this gives users. (You can buy a 128GB eMMC today. And Samsung makes 256GB eMMC chips.)
You mention cheap SSDs. Let us be clear, the RK3399 SoC does not include SATA. So any storage has to be something supported by the SoC. Or converted from PCIe.
Keep in mind if their were 2 x USB Type C, (one purely for power), it might be confusing for users. Some people would want a docking station that supplies power in addition to the video, which means the USB Type C for power only is useless.
What I meant for USB 3.x hub, is that the RK3399 SoC has only 2 USB 3.x ports, (if I understand it correctly). So in order to have 2 x USB Type C AND USB Type A all at USB 3.x speeds, you have to have an internal USB 3.x hub.
All that said, in 1 to 2 years a newer SoC could be selected that has more flexible storage and USB options. Until then, any 2.2 revision board is "stuck" with the RK3399 SoC.
This is one of the problems associated with ARM devices. Intel & AMD both make tablet and laptop focused CPUs & SoCs. Their are ZERO focused ARM laptop processors, today. We have ones that are very close and usable as laptop processors. But, their original design was for media players, IoT, (Internet of Things), etc... Even the newer RK3588 is not quite laptop focused, (dual Gigabit Ethernet in a laptop???).
