Here's some random stats about the popularity of the
maintainers YAML property in the Helm charts in the stable and incubator repos.
To learn more about the
maintainers property, visit the official docs.
Total charts: 285
Maintainers set in 214 charts (75%).
Total charts: 63
Maintainers set in 42 charts (66%).
The vast majority, if not all, of the charts without maintainers are deprecated.
I'm not sure if the maintainers property is mandatory to get into this repository. Given the high adoption rate, it would make sense if it was.
