> for an engineer who knows what he's doing, LLMs are of very limited use
LLMs are very good at code analysis, and finding both security issues and optimization opportunities. Yes, even in code written by highly experienced human engineers. Failing to have an LLM look for places where your code could be optimized is, IMHO, indefensible. It's like shipping your binaries compiled at -O0 - deliberately choosing to waste your users' time and hardware resources because you couldn't be bothered to properly configure and run a tool.
