On-sensor PDAF, will it be as good as mirrored cameras?

Instead of talking about it...I searched around and dug up an early 70's vintage manual focus Vivitar 200mm f3.5 prime that I had lying around. I hadn't even looked at this lens in 15 or 20 years.

When I close focused, it cantilevered out across the room and I was shocked. At an arbitrary focal distance of approximately 9 feet it had extended 17mm. I didn't bother measuring its actual MFD as I was too disheartened.

The whole z axis process might work but it will have limitations I hadn't fully anticipated.
