Possibly an unpopular opinion, but I think we shouldn't even need Fedifetcher. Mastodon should just do this as a built-in feature. Imagine this, it could even be more people focused. It could possibly have settings for people who specifically do not want thread backfilling to work on them, too, just like how you can opt out of search engine indexing. And no, I don't really care to have a discussion yet again about whether or not something like that is voluntary or how bad actors can simply ignore it. But most of the clients I use let me grab any post from the remote instance already. That is effectively the exact same functionality, except my client has to do it, it's an extra step just like clicking through to the original post, which it really shouldn't. Mastodon should just be able to do this with reasonable settings for people.
