> That looks fine to me. I don't think so, the spaces should be able to remove. [`remark-parse` use `collapse-white-space`](https://github.com/remarkjs/remark/blob/daddcb463af2d5b2115496c395d0571c0ff87d15/packages/remark-parse/lib/tokenize/reference.js#L174), let use it too? Just don't lowercase.

@niksy Can you fix conflicts?

@alexander-akait Are you fine with this change?

Why don't we update cache when file actually successfully written?

We don't need care about `performanceTestFlag` that's for debugging.

I've followed the progress for a long time, maybe we can open a PR to prepare for it. But I agree with @sosukesuzuki, we should wait for official release to...

@Josh-Cena Any progress?
