Do explicit optimizePackageImports override or merge with the defaults?

[mmkal]

Summary

There's a short list of libraries documented which are optimized by default: https://nextjs.org/docs/app/api-reference/next-config-js/optimizePackageImports

If we set the list explicitly, will those in that list still be optimized, or should we copy over the list?
