Are we certain we keep all necessary copyright / license blocks intact?

Unfortunately, that's a good question. And, in fact, I'm not sure we aren't in license violation already by using rollup but not distributing LICENSE files that come with the code. If that's a problem, then we may need to consider either checking in the entire node_modules directory (like we do for ESLint) or else going back to not shipping the markdown linter with the repo at all and requiring installation to use.

I did a grep for "Permission" and "Copyright" and came up empty. It also leaves @license JSDoc entries intact. So it seems that we're good. It does not appear to be removing license text or copyright text.

Although that doesn't answer the question as to whether we should be including LICENSE files etc. But if so, that's already a problem. This PR does not exacerbate it, at least.
