Yes. This template is rendered, when a single file wiki is saved. But you need to be careful. Search engines will hit you with a big penalty, if you create spamdexing content.
So you will need to read the search engine guidelines about, how to create a proper SEO optimisations for SPA (single page apps)
If you search for SEO and SPA, there is one topic that always comes up. Server side rendering. Which is exactly, what our /static/ page representation does.
If we use a Node.js client / server installaiton, when the server is started, it will create a TW SPA and keeps it in memory. When the URL is requested, it will send the full SPA to the browser.
So for the browser there is no difference between a single file wiki served with eg: nginx, or a client / server Node.js served wiki.
If you change $:/core/templates/static.content and save it with the client/server configuration, the noscript area is updated with the next browser reload.
