The menial task of updating the interfaces when the code changes is something AI should be really good at, so it's essentially little to no actual programmer time waste

Updating MCP by AI is one time effort.

Having AI re-create what MCP would do for every piece of code that uses a service is massively wasted effort in comparison

It's not question of "model limitation" but of cost effectiveness.
