Worth pointing out that HTML is more ubiquitous than you're making it out to be: just plop a WebView in your native app, and you're done. I know, for example, that the Uber app does webviews in some places; you probably wouldn't even be able to figure out where just from looking at it as a user.

Another case in point: is your dev team going to support PSP devices[0]?
