Many BT uploaders and BT webmasters, who are supposed to be the promoters of the new feature, are now taking a wait-and-see approach to this, reversing cause and effect in the hope that the new feature will first be popularised for leechers, and then they'll adopt it for creating new seeds.
such as some of the uploaders of TGx
Sort of related question: Do any of the torrent indexers with DHT crawler currently index Bittorrent V2 hashes? That would seem like the easiest workaround for finding V2 torrents since none of the general public/private sites have V2 support.
(I'm talking about sites like BT4G, BTDig, SolidTorrents, BitSearch, BTMET, Libtor, etc.)
