With Fabric8 5.5.0, we can enable this feature, but it cannot handle BOOKMARK events until 5.9.0[1]. So, we may need to upgrade k8s client as well.

Would bookmark introduce any regression for users? If so, +1 for not enabling it by default.

> In some production environments, there are massive pods that create and delete. Thus the global resource version is updated very quickly and may cause frequent watcher rebuilding because of "too old resource version". To avoid this, K8s provide a Bookmark mechanism[1].
> I propose to enable bookmark by default
