I can't seem to figure out if it's possible to run the web apps (PWA) without launching Safari every time. That has been one of my main complaint about Chrome PWAs. Everything I launched Google Chat, Chrome would also start. I get that it's Chrome doing the actual work, but I don't use the browser, so why would I want it on my Dock.
I can confirm that you can run web apps created this way on the developer beta without having Safari running, and if you have both running than quitting Safari will not quit the web app.
> Observation: Separating Safari and Web App allows both to run independently. You can open a Web app without opening Safari, you can close Safari without all web apps closing.
