Isn't it more about the accessor and how it's used in existing sites?

If it's behind a method call, perhaps even a parent attribute, there's opportunity to regenerate, long as there aren't too many sites out there optimizing out the access call.

Regardless, it's good to see that we could simplify a few items.

I do want to see use cases on FileList addressed soon.
