Can PWAs act as browsers? Or more technically: Does the PWA concept allow displaying previews of other webpages, regardless of their X-frame-options or similar settings?
I am not currently persueing specific ideas myself; Rather I am interested into whether the current technology would allow to convert apps such as Feedly, whose native apps allow viewing webpages without leaving the app, to PWAs.

No. Standard web security rules still apply.
