changes were made in the industry because of AF447... to teach other engineers some of the difficulties surrounding automation.
New products have included many changes in detailed engineering efforts, including:
Improved sensor requirement, design and qualification tests (including associated engineering process review check lists).
Integration of sensor data from traditional design expectation and alternative sources for improved temperature, pressure and derived speed data.
Extended design assurance test of common mode (e.g. probes icing) scenarios, that cascade into system effects: a) to improve understanding, b) identify improvement opportunities.
Overall reduced rate of occurrence of Autopilot/Autothrust disconnect due to probes and common mode cause - fewer startle events.

Existing products
As suggested by comments above, there may be no cost justification for further hardware, system and software modifications, so there may be less opportunity to fit improved system designs due to component and digital data bus constraints.
