Have you read that description? It's an obscure feature of that single client, and it collects hashes for all files in your public torrents on a central server under developer's control (not cool). I imagine that using that global shadow tracker instead of public peer exchange channels might be useful when you try to hide in plain sight, but how many people actually use it?

It is not the same, BiglyBT uses the ability to attach arbitrary metadata to DHT keys to add comments, including special ones about matching files. It is decentralised, and relies on individual clients having torrents with matching files, and posting those comments to both torrents automatically. Other BiglyBT clients then check those in background, and try to download relevant parts of linked torrents.
BitComet essentially uses a giant central tracker, but for file hashes instead of torrent hashes, and its own protocol to ask for those files. It probably would not be difficult to implement in other clients (if there was a public description), but there are zero guarantees offered for the security of that central database. If I'm not mistaken, BitComet is mostly popular in Asia, where piracy crackdowns happen regularly, and it's highly unlikely that they skipped such data source.
