It turns out that this hash is less common than I thought.
.4% of torrents collected in a set by 2018. .1% of a much smaller set of torrents from more recently.
I am withdrawing this feature request as I do not believe it is worth it to implement.
Is your feature request related to a problem? Please describe
Some torrent files may contain SHA1 hashes for their files. These hashes could provide hints in the future for deduplicating data or finding other torrents to cross-seed.
Describe the solution you'd like
Store the SHA1 hash for a file when it is present in a torrent.
Describe alternatives you've considered
Using file size to find files that can potentially be deduplicated/cross-seeded instead.
Additional context

I don't know if these file hashes have actually been used in practice but if they have it could be quite useful for trying to identify files across torrents as an alternative to waiting for Bittorrent V2 support and adoption.
