For me, it doesn't really matter who satoshi is as long as he never comes back. He/she/they could be anyone, literally, and if they decide to come back without us knowing that they were some super shady, nefarious beings then I guess it's game over. Personally, as long as the protocol works perfectly and the visions of Satoshi is fulfilled, we can let them be and just continue with what we're doing while we're at it and improve the system if there needs something to be improved. But of course, we should always recognize what he/she/they did, and we can do that without constantly asking their real identity is because that's their right after all.
