We don't need guaranteed copy elision, we need CTAD for that. If we have 
CTAD, we can also keep QMutexLocker, as a template, and old code will 
still work, even with QRecursiveMutex and QBasicMutex.

The milestone is std::byte, which which we could put QByteArray on a 
sound basis. And char8_t, which would make QUtf8String(View) fly.
