They already have. 90% of it has been reduced to 60kph and there is only that one spot I took the video on which is still 80kph.
With the crap resurfacing and all the coppers I don't really bother with it any more. A mate was booked up there not long ago and the cop that nabbed him actually said "this road will be will be much better when we finally get rid of you motorcyclists".
Now days most riders head out to Wollombi and the Putty.
