This paper seems like it misses the forest for the trees. The analysis is certainly interesting and the proposal sounds viable, sort of like a sliding window attention with a little more history. But if it is true that the separators contribute the most towards the attention scores, wouldn't that imply that the tokenization scheme can be improved? Introducing a compression scheme seems like patching around that compared to if the model naturally generated a more random attention distribution.
