When a template class takes Ref<T> as a template parameter and this template parameter is used as the return value of a member function, the return value can be treated as unsafe (i.e. emits a false positive). The issue was caused by getCanonicalType sometimes converting Ref<T> to T. Workaround this problem by avoid emitting a warning when the original, non-canonical type is a safe pointer type.
