Honestly you sound paranoid. What if a dev wants to add instrumentation to make sure a page is loaded? What if you have some weird OS version, CPU, or kernel that might crash 1% of app opens?
A web page is not an app. It is a sandboxed rendered template that should not be able to crash due to a web page nor care about what OS, CPU or kernel the user is running. If a user wants to give that information away, then they should be prompted.
