You review the ideas & code at a high level. I feel like you didn’t read the “nit” part. Instead I get review for my flyby patch (no plans to be a mainstay) where the idea is fine, but the maintainer wants me to worry about variable names, spacing, & other BS that doesn’t matter. You get a ton of “please add space here” type comments & the maintainer is putting the onus on you to fix their quirks which leads to a really slow review process full of irrelevant nitpicks. A maintainer should just merge that code & fix the nits themselves rather than expecting everyone to care about their naming conventions. Pull request model in an MS GitHub-like UI encourages this behavior.
