Heya! I was going through the new API and saw there are a bunch of new changes, thought you could use a write up about them.

Hi @frozenprocess. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

thanks for your contribution @frozenprocess! This blog is describing (not always accurately) the changes that are being done in the v1alpha2, which is done in more detail via a general effort of updating the docs here https://github.com/kubernetes-sigs/network-policy-api/pull/333. What would be really valuable coming from the API users, is some more of your/your customers experience with the ANP/BANP and CNP, any feedback, real-world examples or maybe how your configurations have changed/will change with the new API. Also your post mentions scalability improvements, if you have any examples for those it would be also really nice to see!
