------- Additional Comments from Hajime Morrita <morrita at google.com>
I'm a bit worrying about the perf implication of this change since this makes
disabled() slower.
But I'm not sure if there are good test to cover such scenarios. disabled()
might not called that much,
after all.

Let's land this and see how graphs react.
