One challenge for this would be to do this in a version agnostic way. Another is that nothing is using this info at present and we'd have to have a compelling use-case where adding such an API would be useful. AFAIK, net_cls which would allow something like that in v1, does not exist for v2. With all that said, I don't think there are any plans to do this. Thanks, Severin
