As I see it the web is predominantly built with one concurrency pattern.

A client (web browser) can do an RPC to a server

We can't (easily)

do an RPC from the server to the client
send an asynchronous message from server to client
send an asynchronous message from the client to the server

Of these four concurrency patterns three are crippled.

Instant messageing, for example,is trivial if you can push messages to a

Turning web sockets off for security reasons is stupid.

The solution is to sandbox the thing that receives the messages
or if unsandboxed strongly authenticate the messages.
