I think the main thing is even if it isn't it should feel like it is going to be permanent. With Falcon and Bucky we all know they were just playing Cap and sooner or latter Steve was going to be back. Same with Thor, Iron Man, and others. With Ghost Rider when they created Dan Ketch it had been Years since Johnny Blaze had even been seen so it felt more like a real "passing the title" move and not just a sales gimick. Even when Blaze did come back into the Ghost Rider book he was not Ghost Rider he was just Blaze. The problem comes when latter writers want "their" version of the character back and just wave the magic reset wand.
At this point the passing the mantle troupe is tired and played out because we all know within a few years it is going to be reset. It is the same as character deaths. We just know nothing is going to stick.
