How does the mechanical method of controlling the aeroplane ('manual' cable controls or fly-by-wire) have any bearing on the matter?
The systems you mention were all well documented, and have been proven and tested over decades of use. I don't think the same applies to MCAS (yet), and to describe it as a "safety" system is laughable.

My concern is not about whether MCAS is manual or electronic, nor whether the flight controls are manual or not. My concern is the introduction a system with a known delay lag. And secondly one which relies on a pair of AOA sensors, with a known inability to produce consistent and reliable readings.
