187 People asked about duplicating data on a single device for a long time. There
188 are no technical obstacles preventing that, so it got enabled with a warning

196 Note: due to backward compatibility, the range maximum for 'usage' is not
197 inclusive as for the others, to keep the same behaviour as usage=N .
