I have, and Go over here is only relevant as the language Docker and Kubernetes are written on.

Everything we do is written in JVM or CLR languages, JS/TS, and the occasional C++ for native libraries.

You must be joking. Over 75% of software on CNCF is written in Go; these include tools ranging from CI/CD to metrics and monitoring. It may not be popular to write your enterprise applications but it is certainly very popular in cloud infrastructure

		Quite serious, CNCF products are basically Docker and Kubernetes related, that isn't what actual companies care about when moving their compute workloads from in-house into AWS, Azure, GCP, Vercel, Nelify, while paying big boys money to consulting agencies. Many of those products are startups looking for attention in podcasts interviews and the like, and barely part of any enterprise cloud projects.
