Sorry, no - it shuts up too much. Look, there are two kinds of warnings
here. "May be used" and "is used". This stuff shuts both. And unlike
"may be used", "is used" has fairly high S/N ratio.
Moreover, once you do that, you lose all future "is used" warnings on
that variable. So your ability to catch future bugs is decreased, not
increased.
