Yes, with this solution, internally it could be seen a two separate torrents, but if it is an option easily accessible in the client settings, and it is handled transparently as a single torrent, much more people will do it, and the scene as whole would gain with the network effect.
To be fair, I thought of modifying my client privately to do it, but I guess it will only have an impactful network effect if it is distributed as native feature of popular clients.
