The syntax is `udp://[SRC_IP][:SRC_PORT][@[DST_IP][:DST_PORT]]`. As you can 
see, the @ is already optional, so I don't see how it could be removed without 
breaking backward compatibility. And breaking compatibility would defeat the 
sole purpose of the scheme. We deprecated the raw UDP protocol in favor of RTP 
over 15 years ago. But people still insists on using it, and that's outside 
our control.

You will need to elaborate what you expect from VLC, because this request 
seems entirely unactionable to me.
