Bittorrent protocol is missing a way to augment a live torrent

[colemar]

Suppose I posted on many indexer sites a torrent with 23 files.

Issue: after the fact I realize that one file is bad because it has out of sync audio.

What do I do?
Sure, I can do a repack and post it on every indexer site. The repack may contain only the new file or contain all the same old files with the bad one replaced, it does not matter, at least in linux, because hard links allow to have another view of the same files without duplicating the data on disk.
But are leechers going to pay attention? Most likely not. If the indexer site allows editing the old post I can add a link to the repack, but again, what are the chances that every leecher revisits the post?
Not to mention the effort of going around all the sites again to publish the repack.

If I could simply add a file to the live torrent somehow...
