Namespace and rooms

Hello and welcome back team
@George @patrick @Teodor

You added great things again with the last update.
I need your help in a matter. I have been waiting for a long time to add namespaces and rooms to start a project. Will it take a lot of time to add these features? I need to plan for the project. (I need these for the chat area.) I would be very happy if you could give me an approximate time.
