It’s unlikely that you’ll find much support for reconsidering a decision that was already a fading memory when Damien wrote that 4 years ago. And especially now that the SM-2 algorithm has been surpassed in most ways by FSRS, which uses a completely different system for determining new intervals after delayed reviews.
Isn’t the real issue that it was pretty much guesswork? Whether to add the full, half, quarter, or no delay sounds like it was a rough approximation along the lines of “that seems fair.” If it was hard to remember the answer after that period of time, and we know the next interval is already going to grow based on the card Ease – not having it grow even more than that doesn’t seem like a penalty, or all that unreasonable.
