I have 2 questions on Custom Metadata type records:
Is it possible to delete custom metadata records in a subscriber org? I can delete it in the packaging org but how can I send this deletion signal to the subscriber org apart from releasing/installing the whole package? What is the alternative?
For a Protected type of Custom Metadata (which allows access to its object only through its own namespaced apex code) is it possible to package the records as a patch and install it in the subscriber org? Would such records installed as a patch be accessible from the code?
