Do people really clutter their phone with every random website app? Most of them appear to be marginally better at rendering the website for the low, low price of scraping some subset of your personal data.

I use Android profiles for the simple reason that I don't agree some random app needs to know every email or phone number in my address book,much less mine my text history. The few apps I use go to a profile hooked to my ham email address. Still not perfect.

But deep linking via apps? What's the compelling use case again? I don't see one that doesn't work just as well on the mobile web site.
