Hi Caleb, Thanks for your alternative proposal. Unfortunately I could not support it. The word “understanding” has no clear meaning in this proposal, and experience with patch review (and using LLMs) leads me to conclude that such “understanding” is much weaker, more shallow and error prone. Talking about a patch in the world of LLMs is also no demonstration of understanding it.
Importantly, if we “accelerate” as Patrick wants, we must necessarily give up human understanding. In the best case this policy allows some fraction of authors to stop writing code and free up time for review* so that there is some fractional velocity increase at the expense of their reduced understanding. But to accelerate as proposed, this new bottleneck must come under further pressure and “understanding” must dilute significantly, likely relying on LLM for a significant fraction of it, as is happening in the kernel. While this policy maybe aims for the former outcome, the latter is the likely end state given the opinions expressed. If we cannot agree sensible limitations, I would instead support Aleksey’s proposal of adopting Rust’s stronger policy. * this rests on the huge assumption that this would be possible or desirable for these authors On 2026/09/24 04:54:50 Caleb Rackliffe wrote: > I’d support something that boils down to roughly this: > > > > 1.) 2 committers must understand an LLM-assisted change before it commits. > (Perhaps separately we can explore the question of why we haven’t added any > new committers to the core project for about a year.
