question: Is this function here only for debugging purposes or is it actively used? If it is used why not provide a more meaningful message?

Thanks!

const { TransientLazyModule } = await import('./transient.module');
const moduleRef = await this.lazyLoadModule.load(() => TransientLazyModule);

const { TransientService } = await import('./transient.service');

question: Would it make sense to use Promise.all() or Promise.allSettled() for awaiting these imports in parallel for a slight perf boost?

Thanks!
