No, not a clear reason other than wanted to get the product out earlier. We'll work on an opt-in, that does sound the best.

Wouldn't other pieces affect this though? For example, what if the move was e6 and the next e-pawn move was e7. What if a piece was already there, Ne7 (wrongly recognized)? I thought about slowly running through it like this, but it felt like I kept running into problems which are obvious for us to recognize but I wasn't sure how to implement it computationally
