Afaik no one has worked on UDPROS in recent years.
Support in roscpp is OK-ish. There have been some PRs submitted to ros/ros_comm to fix some issues, but nothing too major.
As for rospy, there is essentially no support (I believe this comment by @Dirk Thomas is still relevant).
Note that the UDP transport uses single datagrams for each publication, it does not support sequencing, framing or reassembly. As a consequence, any messages that serialise into a bytestream > MTU will be either truncated or not published at all.

I just wanted to note that UDP isn't supported by ROS in Python atm [..]
