More Network Options

Would be good to have support to WebSockets/TCP/UDP(Like the deprecated network extension on GD4).
REST is not even an viable alternative for game development.

Also i’m unable to write it on my own due the lack of documentation, including on extensions(Are they even supported on 5?)

From the results I have noticed 5 is still in beta stages and has less features than version 4 so to answer your question I would say no.
