If you already have a NodeJS person, it would be far better than having to set up a static-optimized web server from scratch. You can't just replace your big fat Drupal (or worse) site's web root with a bunch of HTML files and have it perform as well as a static-optimizer server.

And even if you don't have anyone on-hand, it is, unfortunately, cheaper, easier and faster to learn all this crap and deploy to Netlify, than it is to set up a solid Web server from scratch (or even get good enough "just a folder" web hosting).
