Why bother writing PRs and commit messages at all, if this is true? Im not opposed to heading there, but I think a huge amount of reason intent & purpose is currently captured there in 99.9% of orgs. And that repository has always seemed like an invaluable repository of context.
I'd like to visit your pleasantville. I dont believe it is real.
Nobody almost ever writes detailed commits at my workplace, but I try to keep the code well documented when I can. Commit history can help sometimes but mostly just to establish timelines.
