Alas, this would create a rampant thread which cannot be joined any more. I guess when it got standardized, they felt that such automatic detach is no good, but did not dare to enforce automatic join either, by some reason. So they chose to std::terminate() which is the worst of them all IMO. See https://isocpp.org/files/papers/p0206r0.html (Discussion about std::thread and RAII).
