I also write pretty detailed PR messages… mostly as comments on specific lines of the PR, either in the code itself if they’re worth keeping around. Or GitHub comments if they’re only of temporary relevance.

But I’m not sad at all if they’re not read. It’s there if people want/need it. If they don’t then it’s easily skipped. I’m also not mad if someone asks me a question that could’ve been answered by reading a comment… different people have different ways of learning and I am happy to show up in whatever mode they find convenient.

If a specific colleague is frequently missing info that was available in comments maybe that’s a growth opportunity for them to up their pace, and I might drop something in their suggestion box, but we’re all learning.
