Per the AF report above, The Rosemount/Thales pitot probes have been problematic for years. Since Airbus insisted the newer -AB probes do not claim improved performance in icing, the prudent course of action for AF would have been to replace all Thales probes with Goodrich.

It sounds like the Rosemount/Goodrich ones have been redesigned because of icing as well. Also in both redesigns it has been to improve resistance to icing not necessarily prevent it completely.
I think we still need flight control systems and procedures (beyond the current) that can deal with this issue as well.
"FEATURES OF MODEL 0851HL
Improved Design Features
In order to meet the Airbus extreme icing conditions specification, the Model 0851HL Pitot Probe has been designed as a replacement for the Model 0851GR. These performance enhancements were accomplished by
increasing the power density in the tip region by 35% over the existing probe, and incorporating the high power density in the drain hole region to ensure proper drainage during severe icing conditions."
