It feels like we should be able to do:
```suggestion
}
std::optional<TraversalKind> getCheckTraversalKind() const override {
return TK_IgnoreUnlessSpelledInSource;
}
```
That way, the check won't waste time repeatedly scanning template
instantiations, for example. If this works, you should be able to remove the
`unless(isImplicit())` from the `AliasPreconditions` matcher.
