Only that QImageReader/Writer do not make it easy to correlate mimetypes
and image format names.

Isn't that exactly what the "keys" part of the JSON provides?  Of
course, there could be some case-sensitivity issues, but mostly easily
dealt with I think.

Keeping the desktop files is the easy short-term option; I'm just
thinking about ongoing maintainance (I've been working on cleaning the
plugins in kguiaddons, which is why it's on my mind).
