It triggers for all, but the python script filters for accesses to
properties that actually should be there. I wanted it to be easy to change
the filtering logic without recompiling everything.

Does the feature detector detector trigger on undefined accesses to *all*
JavaScript objects, or just host objects?

Feature detection is often a pain point when figuring out why a site
doesn't work in Servo -- regular JS errors are logged and detectable, but
feature detection is silent. JavaScript's awesome coercion rules cause
similar issues when a property evaluates to false when it's really
undefined.
