> The package-lock.json file is not only useful for ensuring deterministically reproducible builds. We also lean on it to track and store package metadata, saving considerably on package.json reads and requests to the registry. Since the yarn.lock file is so limited, it doesn’t have the metadata that we need to load on a regular basis.

So I guess there are some performance benefits with npm 7 compared to Yarn 1?
