You can have that today. If you get a USB-C breakout for the dock, it'll treat the Moonlander, or any keyboard, like a normal keyboard. You can not destroy your wrists right now, as I sometimes choose to do.

I’m pretty sure they are saying they want both that keyboard plugged in and MacOS rather than the limited iPadOS; not that they think MacOS is required to be able to plug a keyboard in.

Exactly. iPadOS can’t run a Unix shell and docker, but macOS can.

I don’t even want touch to work on the iPad running macOS. Just let me run my own input hardware against it.
