Can't tell. Possibly yes. You will need to try.

If it is only about protecting the user from as you say "bad usage",
where is the problem? If you need this behavior you easily can write a
little convenience-wrapper for your projects that achieves this goal.
The threading library is designed to allow you the broadest valid usage,
only protecting from agreed misuses. Why should we unnecessarily limit
the libraries API when you can specialize it to your needs?

And even if you might find out that there is a way on windows where your
proposed change allows for a faster implementation, you still would need
to prove that this also holds for other operating systems.
