I agree with the caveat that suppressing, rather than fixing, for a release is appropriate, but that suppression should be removed and the warning should be addressed otherwise, if possible, after the release.

If a warning can be fixed by changing the code, and the result is reasonable and maintainable, and doesn't violate performance demands, then the warning should be eliminated by changing the code. If those criteria cannot be met, then there should be assertions and/or tests that specifically address any issues raised by the warning to ensure that future platform alterations don't violate assumptions made by the code and flagged by the warning. Only then should the warning be suppressed.
