Pervasive checksumming is going to cost a lot of CPU and touch a lot of memory. The data could be right, the checksum wrong as well. ECC double bit errors are recognized and you can handle them how you'd like, including killing the affected process.
I agree, which is why I used the word "mitigation", as in: not a solution.
Probabilistic programming is a theoretical possibility, but not really practical.
