typeorm 0.3버전에 아직 seed기능 안나온걸까요?

$ yarn run seed
yarn run v1.22.17
$ ts-node ./node_modules/typeorm-extension/dist/cli/index.js seed -d ./dataSource.ts
query: SELECT VERSION() AS `version`
typeorm-extension seed

4달전 즈음의 공지사항에 typeorm 0.3버전이 Seeding이 아직 호환 안된다고 되있던데
아직 안나온 거겟죠,,

• /database/seeds/create-initial-data.ts
  Connection이 deprecated되었다던데 제가 못찾은 새로운 seed방법이 나온걸까요 검색해봐도 안나오는데 아니면 없는걸까요

export default class CreateInitialData implements Seeder {
  public async run(factory: Factory, connection: Connection): Promise<any> {
    await connection
      .createQueryBuilder()
      .insert()
      .into(Workspaces)
      .values([{ id: 1, name: 'Sleact', url: 'sleact' }])
      .execute();
    await connection
      .createQueryBuilder()
      .insert()
      .into(Channels)
      .values([{ id: 1, name: '일반', WorkspaceId: 1, private: false }])
      .execute();
  }
}
