I’m very happy to share with you PR 4321.
The PR replaces our current Traffic management concept with an updated, restructured, and rewritten concept.
This is a first step towards making our existing conceptual content easier to find, understand, and expand.
Please take a look.
If you think there are missing pieces or want to request related content be added, please file an issue for us to tackle it as part of a future effort.
Our goal is to publish this concept as part of the Istio 1.2 release.
