I am not so pessimistic. For example they do seem to have a special
case for not warning about
uint32_t = uint64_t & 0xffffffffu;
(at least in 2010 version, no idea what version you use?)
So I believe there is a chance that at least the trivial x >> 32 case
would be fixed (unless it already is, just not in the version you use?).
Thus I do believe it would be a good idea and possibly not completely
wasted time to make trivial test cases out of these and submit them
as enhancement requests.
I don't think I personally will be motivated to, plus I am not even
a paying customer so not really the best person to do it anyway.
