Depends on what you mean by "proxying". Everything you do (serving a Single-Page Application or requesting HN by backend, processing it's HTML and sending the content to your own frontend) will take traffic away from news.ycombinator.com and to another domain - which comes with it's own set of dreadful scenarios. There used to be (and still are) things like https://mreidsma.github.io/bookmarklets/jquerify.html https://mreidsma.github.io/bookmarklets/jquerify.html which allow to inject JavaScript on click (and thus would make it possible to transform that site), but I gave it a shot and HN is set up to disallow this: Refused to load the script 'https://code.jquery.com/jquery.min.js' because it violates the following Content Security Policy directive: "script-src 'self' 'unsafe-inline' https://www.google.com/recaptcha/ https://www.gstatic.com/recaptcha/ https://cdnjs.cloudflare.com/". Note that 'script-src-elem' was not explicitly set, so 'script-src' is used as a fallback.
