I think Canon needs good anti-aliasing of vertical lines to prevent DPAF errors--otherwise the camera could misfocus on aliased false details.

if I may ask a question - why 'd DPAF errors occur when multitude of DPAF sensels participate ( are behind each of the focusing points ) and why 'd CDAF ( I think - and I of course might be very much wrong - it is some equivalent aggregation of a number of sensels participating in the focusing operation ) in cameras w/o AA filters not misfocus on aliased false details ?

Because CDAF is dumb, and DPAF is smart, and sometimes too smart by half. CDAF can misfocus when it finds a local maxima in contrast and stops looking

I am sorry but so does PDAF ...
and it still does not answer the question how so many DPAF sensels ( because clearly it is not just one sensel /a pair behind it/) in a situation when clearly data is aggregated from a lot of them can be wrong at once

Canon DPAF doesn't have sensels, it uses the dual pixels on the sensor.
