You can definitely have all your FEPs point to discussions here instead of socialhub. As prior examples of this go, iirc all of Evan P's FEPs point to his codeberg repo issue tracker, which is arguably more annoying than a federated forum.

@julian it could be interesting to add a like ?explain=true parameter to threads that can show like a modal dialog / banner explaining this post is federated and how you can interact with it from your existing fediverse account. Though I have noted sometimes mastodon fails to resolve NodeBB posts/thread URLs to AP representations and I don't know why nor how to fix it
