Hm... I wasn't really happy about images that do copy on read even if I
didn't tell qemu so on the command line. Now they can start to copy data
and use up my internet connection even without the guest really
accessing the data. This seems to be one step more that I find rather
questionable.

Anyway, same as for copy on read: While we can discuss _allowing_ it in
backing files, it's definitely not suitable as a primary interface.
