Those aren't the main parts of feeling like an app. Feeling like an app means taking an action doesn't load a new page. Feeling like an app means the concept of a page mostly goes away.

I guess that's my point. With instant loading thanks to preload and smooth view transitions, taking an action, while actually loading a new page, shouldn't feel like loading a new page. Should be indistinguishable from a SPA action.

At least that's the theory. There might be other tells that degrade the experience, but not sure what they are?
