Personally I wouldn’t trust it even though so far there have been no problems playing online with official firmware on a modded console. It’s possible they could detect it in theory and Nintendo does not take unauthorized use lightly, even if you purchased the game and Nintendo online subscription legitimately.
Damn, you sold me. Especially if I can still continue to play my legit carts online.
