PWAs feel to me as if they are a way for websites to get around adblocking or any kind of extra browser extension. They are the equivalent as a website wrapper webview as a native app. I equate a PWA similar to an Electron-based stand alone web app (e.g. like Discord). Am I incorrect in my assumptions about PWAs? I know you can run them in browsers, but the intended use is to launch them in their own browser window as a separate process, right?
