问题
I'm struggling to find a definitive answer to this.
Chrome Apps are being deprecated across all OS except Chrome OS.
<webview> is only available in Chrome Apps?
This means I can't or shouldn't use <webview> in an extension (if possible)?

As per further research, testing, and comments:
<webview> are definitely not useable in extensions, only in Apps.
