I would say in something like speedrunning there is tons of information that only exists in discord pinned threads etc., and in the combined heads of community members.

To those who care about that hobby a lot of very useful information would vanish if discord went away. That's not a great state of affairs and discord is a very bad place to keep that information, even at the best of times it's not easy to find things in there. But I think it's probably the case for a decent number of communities.

You could definitely argue that it's not historically relevant, since, if speedrunning as a whole disappeared it wouldn't really matter.
