The basic reason is that software at every level expects TCP/IP. And you can't drop in a translation layer because it will require at least the same amount of overhead as "real" TCP/IP.
It is not a local problem, it is a global problem that affects basically every single piece of non-trivial software in existence.
Even if you construct your datacenter with the new protocol you will run into problems that you can't run anything in it. Want Python? Sorry, have to rewrite it. And every Python library. And every Python application. Then you need to deal with problems that people who can run their scripts on their machines can't run them in datacenter. And so on.
The reason nobody wants to do this is that they would be investing huge amount of money to solve a problem for everybody else. Because the only way to make TCP/IP replacement work is to make it completely free and available to everybody.
There are much better ways to allocate your funds and precious top level engineers that let them distance themselves from competition temporarily.
