> Despite how well this new approach has worked out, there's still one big limitation that remains: it's currently Windows only. However the official WebView2 roadmap lists macOS and Linux support on the way, so it looks like it should be possible to port this approach to both other desktop platforms in future.

I'd be wary of betting on roadmap features, even if well-intentioned you have no control over the dates/priorities.

If your primary customer is Windows, yay! But as a replacement for existing options it's not mature yet.
