So... are we ready to go? 🚀 👍🏻

[TomUdr]

For me this issue seems to very serious because it prevents from effective monitoring and alerting k8s resources based on their labels. I wonder why this doesn't have so much attention if the solution was done in May 2021, but still not being merged and released. Maybe community is not using this helm chart?
