I don't think it's a good idea as-is. The target core clearly
differenciates between demo mode and production mode read only, and some
drivers already expose attributes for these.
I have a big series in progress to clean the mess around this area
up. So for now please don't add anything here, it should become much
simpler after my changes, and I might be able to incorporate something
like this after the main series.
