That's exactly how the 1DX worked that I used in April.
They will not rework the whole viewfinder and AF point display system. But they might have figured how to momentarily light up the AF point in AI Servo, as is done on other Canon camera bodies (sans 5D3). Such a last minute change would not necessarily be reflected in the posted user manual.
The lack of momentary illumination in AI Servo is the issue that people complained about originally, but (as happens on the Interwebz), a few persistent people have elevated this to a crusade against the entire transflective LCD viewfinder design (originally introduced on the 7D).
This design seems integral to the whole "Zone AF" system, so there is little chance that Canon will change this, in my view.
