UDP socket in Tokio does not implement `try_clone`

Forgive me if this is not the right forum for this kind of question.

When looking at the std::net::UdpSocket there is a try_clone function that I expected would be available for tokio::net::UdpSocket as well, but looking at the implementation reveals that no such implementation is available (looked in the Tokio repository at GitHub) .

The implementation in tokio::net::UdpSocket is based on the mio::net::UdpSocket, which does have a try_clone function, so the reason for not implementing it does not seem to have anything to do with lack of the same functionality in mio, so why is there no try_clone implementation?

Was it just accidentally omitted, or is there a specific reason for why it was not added?

Since I got no replies, I created Issue #1307 and a PR for fixing the issue in case anybody is interested.
