Right! I had the exact opposite view when reading this comment. The good timeline is where one of (or perhaps a small number of) the open source harnesses becomes so dominant that the models compete to have the model that is the best trained to work with that harness. (I'm hoping this would be Pi, because it's my favorite, but mostly I just want it to be some model-agnostic open source harness that wins.)
It won't be Pi because there's really no singular Pi that is broadly useful without explicit configuration of plugins. Pi requires plugins to do lots of things that are OOB on other harnesses that people care about. MCP, OpenTelemetry, etc. It may be some offshoot or something built on top of Pi that is more standardized, but it won't be Pi.
Realistically, it's never going to be Pi, for the same reason that video game consoles are always more performant than PCs for a given hardware spec.
There's no canonical Pi harness, it's too variable. There might be a world where something Pi based is the target, like OMP, but then you have to hesitate when you start extending the harness because you don't know what effect any given extension will have on model performance.
