in a use case i have for something _like_ bloom filters (though i want to evaluate Cuckoo/Vacuum/etc) i have an immutable collection of changes that happened during an event, and need to query if a specific change type is in that event. Given that it's a historical event, there's no need for removal. My concern (due to my specific application needs) is primarily storage size and query speed.
