Topics, AFAIK, same as feeds are managed. Someone needs to add a community to it for it to start popping up in the topic. That relies on moderation and probably would work better with time the other way round - if it was the community saying which topic it belongs to and moderation would only inspect connections flagged by reports
But then, most of communities come from Lemmy, where there is no concept of topics and tags. In which case, it would have to be possible for someone from outside of community to connect it to a topic. A vote maybe?
But then, that would open up possibility of malicious connections
IMO in a way, topics is like tags for communities. A post can have a tag, you can display posts with given tag in a community, but there are no strict rules about how tags connect with communities.
But then, topics should not be created based on most popular tags. I can imagine, for example, privacy community having a lot of Microsoft tags
