This is quite good advice, I feel the “we have to do this anyway” line is more like… “so we might as well make it easy for ourselves”… eg write code that works, you self tested it through tests and manual if needed, so the reviewer doesn’t have to get bogged down in actually running it (start by adding screenshots for this but graduate to not needing them). Keep PRs as small as possible, aka multiple PRs streaming after each other for a single feature card, get the PRs in as soon as valuable and don’t block for nitpics but the shared expectation you start to agree on things that are better and they happen with the next changes.

The general mantra being that “if it works then it shouldn’t be blocked” and developer can choose to improve the maintainability there and then or delay it to next or later PRs at their discretion. After all you trust each other.
