Hugo builds and Jekyll builds are basically instantaneous even for really large websites. I mean less than one second. Like 30ms. You don't even see it happen. Migrating your manually crafted HTML pages to something other than NGINX or changing the theme or website is going to be such a pain in the ass you're going to wish you never thought of this "minimalist" way of doing it. If you look at the website of the guy above at superkuh.com it looks like shit (subjective, of course), doesn't even have a TLS certificate and above all would be an extreme pain to change the layout, design, deployment, etc. I don't even know what to say about this chart in his last post at http://erewhon.superkuh.com/pictures/blog-posts-vs-blog-post... although I must admit it's really funny.
