I think Jehan's idea is that applications should be able to claim to be *less*
equal than others for a given mimetype, i.e. that GIMP could declare 'I can
open JPEGs, but you should probably use something else by default'. Obviously,
if the user explicitly set GIMP as the default handler for image/jpeg, it would
override this priority.
Distinguishing things like 'native' and 'equivalent intent' filetypes seems
tempting, but I suspect it would end up with a lot of awkward grey areas. If
this is a problem worth solving, I'd be more inclined to make a numeric
priority scale, something like the shared-mime-info database uses for assigning
mimetypes to files (which allows e.g. ODT files to be recognised as ODT rather
than general zip files).
Another approach to the stability issue (e.g. GIMP 'taking over' the JPEG
mimetype) is for the desktop to fix it: if you open a JPEG file and there isn't
already a default application for that, store whatever it uses as the default
application, so it won't change unless the user manually changes the
association or uninstalls that application. I think that could be done without
changing any specs.
