What information does this actually provide over and above the hw is not
executing the ring we expect? How have you used this, how do you plan
to?

As it stands adding more fragile loops is just increasing the potential
for an OOPS in that code, even more so as we can eliminate the current
dangerous list iteration for extracting the current ctx object.
