We've caught some bugs by running random combinations of pre-written agg pipeline stages and comparing results with different knobs and feature flags. These pipeline stages are simple, to contrast with the complicated stages that the other fuzzers create. This will find the "glaring" issues more efficiently compared to other fuzzers
