Worth mentioning that there's a comment updated in golang.org/x/net/websocket:

    This package currently lacks some features found in alternative
    and more actively maintained WebSocket packages:
        https://godoc.org/github.com/gorilla/websocket
        https://godoc.org/nhooyr.io/websocket

It's used in k8s.io/apiserver/pkg/util/wsstream/stream.go, so perhaps that should
be reviewed if the alternatives are better for how it's used.
