Maybe, maybe not.  For the backends/scanners where these are marked as
advanced, is there another less-advanced way to set the scan area?
For example by choosing a paper size like A4 or Letter.  If there is, I
think I would classify the well-known scan area options as advanced too.

# Never mind that A4 is of course extremely ill-defined as a scan area.

Given that there might be less-advanced ways of setting the scan area,
mandate might be a bit too strong but we could recommend something of
course :-)

Hope this helps,
