> can you elaborate on the additional value provided in regards to a simple webview?
The proposed value of retrokit (when it's more progressed) is a much smaller library/file size and the reduction of a potential attack surface in regards to fingerprinting, privacy and security.
Legacy encryption APIs that are outdated, Plugin APIs that are from the Netscape-era, "navigator.plugins" and old stuff that's not actually providing any value anymore is being removed as well - due to the history of e.g. PDF files or Java applets being such an oftentimes exploited plugin.
The idea is to have a webview that's focussing on the rendering part + websockets for local interprocess or webapp-to-webserver communication. At a later point in time my goal is to bundle it with nodejs, with the idea being that the "local backend" in nodejs allows all the flexibility you need to port networking and OS interactions; and the webapp representing the UI process that's separated (from a security perspective).
