Description Brent Fulgham 2020-11-04 17:01:53 PST 
WebKit has long had a sandbox rule granting the ability to issue iokit-open operations if a particular security extension was granted to the process. The WebKit processes are known to never grant this extension, so this rule is not needed.

We should remove the rule to reduce sandbox complexity and increase the speed of sandbox compilation.
