Re: [whatwg/dom] Simple EventListenerOptions feature detection (#491)

To me unreasonable starts when I have to call the API to see if it works.
Getters don't work in older webkits that still haunt Android in large
numbers, so you cannot use them, because they throw SyntaxErrors which is
the worst thing that can happen to feature detection code.

I think ergonomics should be a consideration in API design. Here it
certainly wasnt and, again, it is a special case because the API change was
not backwards compatible.

Yeah, that's how you can detect dictionary member support for a large
number of APIs. Why is it unreasonable? Also, why don't you use an object
literal? Seems a little simpler.
