Is there any reason why this work couldn't be done it parallel with kernel development?
There are parts of the kernel that are only touched rarely (ex. block/deadline-iosched, though there are probably better examples).
It seems as though this type of analysis might be good long term project.
Of course, if it is truly infeasible for any but the least interesting parts of the kernel then it is a waste of time.

I suppose that since there's a high chance of it happening, the question boils down to: "What wins when the decision is between ABI compatibility and provably secure?"
