Fuse filters, designed to operate with sets containing more than two elements, encounter specific challenges when a block includes only one element. In such instances, an additional upper layer is required to manage the situation effectively. This aspect was not deemed essential during the initial benchmarking phase, leading to its exclusion from the implementation at that time. However, it is recognized as a straightforward issue to rectify.

Another point of consideration involves the re-seeding process within the context of a 50k mainnet dataset. Preliminary recollections suggest that re-seeding did not occur within this dataset. Nevertheless, a thorough verification is pending, as access to the necessary computing resources, specifically a laptop, is currently unavailable. This verification is crucial for confirming the initial observations and ensuring the robustness of the data handling procedures employed.
