Out of curiosity, are there any other methods in the DOM that treat
undefined as the empty string? If not, is there really a reason to
make these two functions different?

An alternative would be to not mention behavior for undefined at all
and let it be whatever the default is for WebIDL once that spec makes
up its mind. It seems more important to me to behave consistently with
other methods than to have any specific behavior for undefined.
