Seems like a reasonable solution to me.

I'm just following @zkat's posts, they're the magician behind this. (Can't wait for cipm)

You probably already did this, but just in case: If we have a documented update process for these things, make sure it removes the package-lock.json and replaces it with a new one. I see, for example, that remark-cli is now up to 4.0.0 and we might want to update soon, I imagine.

Do we want to backport this? I feel like the discussion about what to do with remark hasn't quite finished, so maybe we should hold off. On the other hand we've already backported some of the remark-cli changes to v8.x, so maybe we need to bring this back too.
