So it's not that Matthias disallows them to use it, yet it won't happen. He could relax the license restrictions to make it work though. For FreeArc, switching the license to GPL2 would be sufficient (or double licensing with GPL2 as option). For 7-zip, he would have to use something permissive and I doubt we'll see it (though no doubt it would be a nice move and accelerate PackJPG adoption).
