I can't see how it would diminish unless you are literally working on public domain stuff. Unless stuffing context becomes cost effective and will not affect AI reasoning (this will be much harder), I don't see why context engineering is here to stay until we have close to AGI.

In think in all cases where I've seen it compared CC performed worse than a minimal harness.
