Oh yes. If we go back further and make IP 64-bit and specify that all endpoints should get a /40 to be assigned to up to 2^24 network endpoints per system and then left out the concept of ports entirely, we could have saved probably ten thousand human lifetimes of coding. Ipv4 addresses are 32 bits and ports are 16, so the above would only have cost 16 bits. It's hard to have that much foresight, but I would not be surprised if it was suggested and shot down.
