The modern way of doing this would be to use a string enumeration in IDL. enum EventThrottlingBehavior { "responsive", "unresponsive" }; attribute EventThrottlingBehavior? eventThrottlingBehaviorOverride; Also, is there really a need for this to be nullable? It seems we could just return "responsive" by default. Finally, given your comment, shouldn't this be in a #if PLATFORM(IOS) block?

nit: It'd be nice for those tests to have a description("...");

Nice, will do that.

I made it nullable to remove the override entirely.

It only impacts iOS, but I'd prefer to not conditionalize the internals API because it makes cross-platform tests harder to write.
