While I don't have the Pimoroni VGA board, nor any accessible VGA monitors, I will try to implement USB-Host keyboard support.

I could make a package that adds boot scripts that when a usb keyboard is attached, a keyboard console input is created.

Then that could in turn be configured with any monitor as output.
The displayiotty driver is able to accept any displayio display object.
