Something similar to what you describe is the status quo - that is when a
client has an existing h2 connection and needs websockets it opens a new h1
connection (which then transitions out of http into 6455 on tcp).

There are several sub optimalities here, but the one that is the driver for
this draft is the websocket operational community reasonably wants a path
to move off of h1 dependency (this is frequently articulated as websockets
being left behind) and these additional connections.
