Is there a good reason we cannot delete a launch plan? We would like to remove some old launch plans beyond just deactivating them. I imagine handling a cascading delete might be challenging and not supported.

Some other workflow may depend on it

@freezing-airport-6809 Do you mean that 1 launch plan can apply to more than 1 workflow? (I understand that 1 workflow can have multiple launch plans, but reverse is not clear)

No you can compose a workflow with other launchplans
