Are we really to blame for that? If the extension is not recognized,
then we use a heuristic in order to determine the file type
(the heuristic has not been implemented for images so far;
see src/Data/Convert/Generic/which_format.cc).
We might generalize that, but I am not sure whether this
would be a good idea, since the heuristics might not be reliable.
