Reproduction

This happened in a private repo to which I cannot give access.
I'm trying to list everything relevant here.

Thanks for reporting @frederik-b! Agreed, for any rule that doesn't have a converter, we should add that in. In case of jsdoc-format, https://github.com/gajus/eslint-plugin-jsdoc looks like the go-to ruleset per https://eslint.org/blog/2018/11/jsdoc-end-of-life.

Accepting PRs to add in a converter. docs/Development.md has a root overview for how to get started. Within that, docs/Architecture.md#rule-converters talks about how these converters operate.
