The engram idea is actually technically clever but imo sees the solution from a bottom-up approach while Louf's real argument is a top-down view. His solution (declarative specs) solves that by centralizing the spec, making it versioned and composable, independent of any actual model.

Engram layers just move the coordination problem earlier and lock it in. Coordination problems between models & providers would still exist, requiring a layer injection in each open source model and another variant produced for each. Users would still need to chose between "Qwen-8b" and "Qwen-8b-engram" x model families and sizes. Is that cleaner?

Fair point. I don't know if it is cleaner or not.

The issue with a top-level spec, that I can see, is that models fall back to their training when it comes to tools. This is why I recommended the engram approach, because as far as I can tell the problem is a model problem not a systems problem.
