Since zstd was added in btrfs there are people wondering why not lz4 too. The wiki paragraph [1] cites a couple dead links as explanations on why it's not a good idea to have lz4 in btrfs.
I think it would be nice if someone can write that information back in the wiki, or for the very least write them in a mailing list message that can be linked there. -Alberto 1. https://btrfs.wiki.kernel.org/index.php/FAQ#Will_btrfs_support_LZ4.3F
