Regardless, I don’t see that it’s possible to get rid of TCP/IP in any meaningful perspective really. There’s millions of devices around that support TCP offload, thousands of thousands of network equipment with routing processors and ASICs onboard. See ipv6 transition as a good example, and we’re much, much more ready to ipv6 than to a new tcp. There’s a ton of artifacts and limitations in the stack that don’t make sense today - tcp ports as connection ids being one of them - but that’s something that’s taken care of on L7. Transport layer is a different beast though.
