> than what I would naturally find worthwhile to write on my own.

I take issue with that statement. There's nothing "natural" about documentation. You're not "naturally disposed" to writing a certain level of documentation. It's a skill and a discipline. If you don't think it's worthwhile to write documentation, that's not a "natural failing". You're making a judgment, and any missing documentation is an error in judgment.

I meant "natural" in a context of having more urgent immediate priorities than extensively detailed documentation at the commit level — not an error in judgement, just a tradeoff.

If a given project has time/budget to prioritize consistent rigorous documentation, of course it should consider doing so. AI's ability to reduce the cost of doing so is a good thing.
