The driving idea behind mirrorless was to allow smaller cameras to be made.Greater AF accuracy came later as the technology improved. Still, in low light with subjects coming fast towards the camera this may not be true.
The hybrid viewfinder has the merit that the user can choose to see either the optical or electronic view. The optical is better at showing the subject in real time with no pixel artifacts, flashing, blocking of shadows etc annoyances of the electronic, and it would have the advantage of a dedicated AF sensor module (which has both advantages and disadvantages). The EVF mode would then facilitate zoomed-in views, peaking, histogram etc. or showing an exposure simulation, and could be used for video. In my opinion the merits of the hybrid approach are significant.
However, the quality of the optical view would suffer due to the hybrid implementation. I believe this is why Nikon didn’t implement it: too much fidelity loss on the optical side.
An interchangeable viewfinder would be a better solution IMO. Dedicated optical and EVF modules could be swapped.
Not only would the optical view suffer in a hybrid version, much of the advantage of a mirrorless system would be gone as well (e.g the option to have small backfocus, getting rid of the mirror system with its production tolerance and wear-and-tear issues. OVF and EVF are too much different to make them simple swappable modules, too much other parts of the system would have to change as well in order to have both perform optimally. A hybrid viewfinder might work in systems with a fixed lens or a very limited lens range, but that's about it.
