So, why would Cessna all of a sudden be worried about corrosion?

Only the military aircraft were zinc chromate'd (I think Reims did theirs also), Cessna was cheap.

Detected corrosion could, in most cases, indicate potential metal fatigue. The typical corrosion program is initiated to visually detect the possibility of future issues. That is why the CPCP program, if initiated, will eliminate the need to perform the SIDs on an calendar time frame and only require the SIDs on a hourly time frame.

But it's really a non-issue for Part 91 operators because we won't be required to comply in the USA unless further action is taken by the FAA.
