In the Comment #26 API, why would you ever do that? If the Handler thinks it
can display every image format ever invented, it could just as easily have a
rule like "always pick the first type the CM offered".

You could make "" equivalent to the first thing in the CM's list if you wanted
to encourage that behaviour, but I expect that real Handlers would want a rule
more like this:

    if (supports audio/speex)
      that's the smallest, use it
    else if (supports audio/ogg)
      that's pretty small, use it
    else if (supports audio/x-wav)
      oh well, that's not so bad
    else
      either
        no particular preference, let's try the first one?
      or
        there's nothing here that I know I can handle, fail

(Using audio here because there isn't such an obvious order of precedence for
images, but for images you probably want JPEG > PNG > GIF > BMP > other, or
something.)
