As it stands now, the BulkChangeTable cop flags uses of change_column_null. However, there is no corresponding method on ActiveRecord::ConnectionAdapters::Table to replace it with as there is with change_column_default and Table#change_default. The closest thing is Table#change, but that requires the developer to repeat the entire column definition (which is why change_column_null exists in the first place in addition to change_column).

Am I missing a reasonable replacement for change_column_null?
