:)

Makes a lot of sense, and you can maybe even implement that when a
userspace program is doing the packet propagation, but for topology
testing I think we should start with the simpler groups thing. And as I
said, the userspace propagation will actually need to turn off in-kernel
propagation which fits setting airgroups to 0.
