Yes, that's what I'm referring to.
I still think it can be good to expose them somehow, as checking for undefined
on an object somewhere is easier than checking the value after every set, or
catching an exception on every set.
What'll actually happen, if they're not exposed for easy testing, is that
people will just use Modernizr (or some hand-rolled equivalent) to test for the
values they need, store the results in an object, and then use that object for
easy testing. I don't see a good reason to require this when it can be done
for them.
