The issue being that in the original question “drop-in” implies complete, that’s what being a drop-in replacement actually means in other contexts. If it’s not complete, then it’s not really drop-in, even though I don’t necessarily disagree with your definition. You can be right, and parent can be right too, IMHO. The FAQ question is stated ambiguously and in misleadingly black and white terms, and the answer really does look kinda funny starting with the word “Yes” and then following that with “but… not exactly”. Wouldn’t it be better to say drop-in is the goal, and because it’s not complete, we’re not there yet?
