Currently QImageReader and QImageWrite are only able to tell which formats they support using format names. It should be possible to instead get the mimetypes. For the built-in types the format-names matches extensions, but there is no guarantee the same will apply to 3rdparty plugins.
This extension can be implemented using the JSON metadata of the plugins.
