SU binary cloaking?

In doing my taxes, I noticed that the H&R Block app tries to execute su (which I promptly deny) and then nags about my device being compromised. It's obviously not, but it got me thinking: Since we're operating in the kernel now, I figure that we should be able to prevent apps from seeing the su binary at all unless we as the device owners explicitly want the app to be able to see it. Maybe even do something like allow creation of an app whitelist and/or blacklist.

If it's tricky to pull off, make it a pro feature (I paid for pro.)

I imagine this would fix Android pay as well (though I don't use it so I don't care) but it might be a motivating reason for others to want such a feature.
