This would be so amazing. In order to access most vanilla services like redis, postgres etc. you need to deploy a bridge https://github.com/zquestz/ws-tcp-proxy

CloudFlare/Deno etc. all have these workarounds around tunnelling but all that would disappear with this protocol. I made a service for writing servers on the web (https://webcode.run -- somewhat abandoned at this point but it is still running), and a big problem with the approach was the web's inability to make TCP connections.
