Heh, I've been shipping software for Windows one way or another for about 20 years. I just hadn't used Edge's WebView2 in anger yet, and now I probably won't.
Edit: And I've generally followed the "bundle every dependency" approach. As far as I can recall, the only dependency in a shipping product that I ever delegated to an external installer was the .NET Framework (before the .NET Core reboot). And IIRC, that did trip up a few users; thankfully, that was only a consumer app.
