I can't say I'd second it -- at least not for anything outside of demos. You can't set custom headers which means you can set the recommended OWASP security headers and you'll get an F score on Mozilla Observatory. This will also not let you set proper caching headers which can mess with performance or just be incorrect like with service workers. A small additional nitpick is that you will need to do your own gzip and brotli compression instead of that being done by default (which is easy to forget about, but at least it gives you the flexibility to support Brotli and future formats like zstd whereas other providers you only get what they decide).
