Not everyone does research like you. And it is definitely not rude to ask have you heard about x and your thoughts about it, especially if you tried something and it didn't work it could spark a good discussion.
Fusion is the main idea behind solidcraft as far as I know. But it is NOT aiming to be a copy of anything featurewise unlike most stuff associated with artcraft (and solidcraft is not an official artcraft app despite the name, at least not yet).
This is indeed the most exciting thing. It feels a bit scary how good the frontier models are at creating stuff with these apps (that are like a few days old and very incomplete pre alpha stage yet already somewhat functional). The future is happening and I just spent a day rethinking my whole life.
