So I thought torrents could fix this. But that’s already in the FAQ

Why do you not make the content available to download via torrents?

The truth is that people are only willing to seed the content they are interested in and not obscure content that nobody has heard of. Direct downloads ensure full availability by allowing all content to be available for download, no matter how obscure it may be.

Additionally, as content in sets are always being added or updated, they naturally also have to be updated anywhere else they are available. Torrents are impossible to update without using BitTorrent v2, which has support for mutable torrents but is not widely adopted yet and has caveats.
