How hard to introduce Elixir's Phoenix Channel support?

[justgage]

I understand that htmx supports WebSockets in their most basic form but I'm wondering how hard it would be to extend it to support Phoenix's "Channels"

Here's a basic example:

let socket = new Socket("/socket", {params: {token: window.userToken}})

var chan = socket.channel("rooms:lobby", {})

chan.push("new:msg", {user: ...})

chan.on("new:msg", msg => {
      $messages.append(this.messageTemplate(msg))
      scrollTo(0, document.body.scrollHeight)
})

It's not much different than raw WebSockets but has some extra features.
