Today, WorkerTargetFront is instantiated by TargetFactory.forWorker callsites like this one: https://searchfox.org/mozilla-central/rev/06d5d5ae4396be85f26e8548323ee6c12e7bce4e/devtools/client/debugger/new/panel.js#71-73 const [response, workerTargetFront] = await this.toolbox.target.client.attachWorker(worker.actor); const workerTarget = TargetFactory.forWorker(workerTargetFront); But we should rather let protocol.js auto-marshalling instantiate all the fronts, here, during RootFront.listWorkers request.
