It seems pure HTTP tracker + Torrent is good enough.
edit: Not opposed to the idea, just curious what makes you pick IPFS over the existing alternatives.
I personally had no interest in seeing the decentralized one either, but there are people who collect digital things for some reason. In that case would've needed convergence on one JSON format at least for the 99% use case of still images, and agreement to put the heavy assets on IPFS instead of HTTP (it was a mix). Maybe axe some of the confusing features like editions.
