While I don't use this feature, there are developers who do. It's useful when running migrations and changing branches. I'm raising an `ActiveRecord::IrreversibleMigration` exception in every `drop_table` migration because these migrations were all done before version 1.0.0, and so making all of them reversible would be too much work for little benefit.
