Adding to Luis reply:
The short answer is no, but we're totally open to such a contribution
in this area. We thought about it but it was never a priority, so there
have never been enough resources to get it done properly.
The long answer is that it should be pretty easy to implement by having
your own PodSubnetsDriver, very similar to the default , that would
do that logic. While we would totally welcome such implementation
upstream, you can also easily keep it in another Python package and use
entrypoints to configure Kuryr-Kubernetes with it.
