2. Only a tiny group of people care to "card count" Wordle to rule out words that have already been played because they think that sort of min/maxing is fun. Most people don't even think about that, so whether Wordle reuses words every few years is trivial to them.
That isn't a correct diagnosis; people have heard of aahed. You'll find it naturally in the expression "[someone] oohed and aahed".
People don't want aahed, and their instinct that it shouldn't count is reasonable, but unfamiliarity isn't the problem with it.
