Probably my best story of “zombie flags” was when this guy accidentally deleted a production table. We disabled the feature flag, disabled some code written after it had been turned on and expected it to be on, then restored the table from a PIT backup. Finally, we reverted the code changes and feature flag. We were back up in a matter of hours (the table was hundreds of gb, so it took awhile to delete and restore). Some customers noticed the option missing from their options screen, but 99% of the customers never noticed the feature downtime.
