I think the comment still holds. We just assume that the property is there at runtime, rather than explicitly check.

Given that this is now a compile time switch, I suggest wrapping the entire function body in:

#if !HAVE(AVPLAYER_VIDEORANGEOVERRIDE)

Rather than compiling a function with a return at the start of it.

I considered that (or doing a #if/#else/#endif, but thought it might be confusing for previous OSs, especially given the existing comment. But sure, I'll re-write the comment to be more explicit that the wrapped behavior is for when this API is not available.
