The point for this patch is to identify if RAID/RST mode is enabled or not. Based on this, ubiquity should consider any case in which the user is able to install Ubuntu indeed. In your case, I think ubiquity can use is_removable (https://git.launchpad.net/ubiquity/tree/ubiquity/misc.py#n230) function to check if external USB / USB-C drive is plugged or not, except for USB boot device.
