please recheck it - i didn't apply any changes at rollup config, but i upgrade ESLint to the latest version, so maybe it's solved now. just to let you know

i assume we didn't not finish eslint setup for rollup.

I also think that additional setup required, because we getting this kind of issues from CodeClimate+ESLint bind: #101 (review)

i don't know maybe it's a good warnings...
