There should be no function object in that case.

Which brings up the issue that it's unclear what it means for an API
to have latent support but not having been activated with <feature>.

If a widget UA has an implementation for window.frob() and frob()
requires <feature> activation, what should happen when frob() hasn't
been activated with <feature>? Should there be no function object for
frob()? Or should it be there but throw upon calling? Or something else.

Please specify this.
