As we gather more telemetry from systems running with IOKit method filters, we have identified additional methods that are needed for normal use cases. Per our plan, we will unblock those cases and consider further hardening in an follow-up patch once have worked with framework teams to reduce these needs.

No -- these were shown in telemetry to be used by AGXDeviceUserClient, but not by IOSurfaceRootUserClient. >> Source/WebKit/Resources/SandboxProfiles/ios/com.apple.WebKit.WebContent.sb:447 >> + 38 > > Is 42 also needed here?
