[For this line](https://github.com/Everlane/async_cache/blob/master/lib/async_cache/workers/sidekiq.rb#L11): ```ruby sidekiq_options :unique => :until_executed ``` If the project doesn't already have the [sidekiq-unique-jobs gem](https://github.com/mhenrixon/sidekiq-unique-jobs), won't this option line just be silently ignored, and uniqueness bugs can creep in?
