C가 소멸자에서 발생한 예외를 처리하기 위해 중첩된 예외를 사용하지 않는 이유는 무엇입니까?

<code class="cpp">#include <iostream>
#include <sstream>
#include <exception>

void rethrow(const std::string& context, ...) {
    std::ostringstream ss;
    ss << context;
    auto sep = " : ";
    (void) ((ss << sep << args), sep = ", ", 0)...);
    try {
        std::rethrow_exception(std::current_exception());
    } catch(const std::invalid_argument& e) {
        std::throw_with_nested(std::invalid_argument(ss.str()));
    } catch(const std::logic_error& e) {
        std::throw_with_nested(std::logic_error(ss.str()));
    } catch(...) {
        std::throw_with_nested(std::runtime_error(ss.str()));
    }
}

int main() {
    try {
        outer("xyz");
        outer("abcd");
    } catch(std::exception& e) {
        print_exception(e);
    }
    return 0;
}

void print_exception(const std::exception& e, std::size_t depth = 0) {
    std::cerr << "exception: " << std::string(depth, ' ') << e.what() << '\n';
    try {
        std::rethrow_if_nested(e);
    } catch (const std::exception& nested) {
        print_exception(nested, depth + 1);
    }
}</code>

exception: outer : abcd
exception:  inner : abcdabcd
exception:   really_inner
exception:    too long
