From the testing in the linked BF, I believe that SERVER-78357 has caused agg_wildcard_fuzzer test files to take ~4x longer than before. That ticket was a correctness fix that we don't want to revert. We should do something now to stop the hot BF, and decide separately if it's worth it to do a performance investigation to see if there are ways to improve the SERVER-78357 implementation.
