This will cause 3D printer usability to go down massively. A bit like the multicolored tracking dots - https://en.wikipedia.org/wiki/Printer_tracking_dots that causes the driver to tell you "you can't print black and white as you're out of yellow".

As far as I know, the tracking dots aren't even a legal requirement. Nothing stops you from making a printer without it, unlike is the case here.
