Nope. This is the worst thing you can do - set rclone mount as a torrent program destination. Any byte in your file changes, rclone will start uploading all file from the beginning. It is not rclone limitation but how most cloud storage works.
Most torrent programs allow you to move finished download to another folder. This is the best approach.
Understood, but if the torrent is made up of hundreds of smaller files, then this should not happen.
can ignoring changes in the metadata of the files here help ?
Let's assume that once a file has been downloaded, there will be no changes to it. It might be read if the torrent is seeding from that portion of it.
