### Sadece modern Python

Tamamiyle standartlar **Python 3.8**'nın type hintlerine dayanıyor (Pydantic'in sayesinde). Yeni bir syntax öğrenmene gerek yok. Sadece modern Python.

"description": "`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic \"Bookmark\" event  will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `\"k8s.io/initial-events-end\": \"true\"` annotation. Afterwards, the watch stream will proceed as usual, sending watch...

      This caused a few issues:
      * Ports are required in Istio, but not in Kubernetes. This can result in broken traffic if ports are not configured as Istio expects, despite them working without Istio.
      * Ports not declared as `HTTP` would match *all* traffic on that port, making it easy to accidentally send all traffic on a port to the wrong place.
