Does calling register_workflow after worker.start() support ?

[vnghia]

Hello I am working on a dynamic workflow scenario where the worker will watch filesystem change in one folder and dynamically registering/deleting workflows. But right now I am seeing that if I call register_workflow after worker.start(). The workflow is registered with the engine but isn't registered with the worker itself (the "Registered Workflows" section in the worker does not have the newly created workflow and trigger the workflow results in an error because no worker can run it). Registering workflow before starting worker works well.

Is it a bug or is it expected behavior ? Thank you very much!
