Thanks for this post, it highlights things that are very important and yet often remain unspoken.
If your org is doing code reviews, it's worth writing something like that down and referring everyone to it.
It will not only push reviewers to be considerate (as is recommended here) but it will also make people who send PRs feel a lot more comfortable. You gotta admit that sending your first PR can be pretty intimidating sometimes, that pressure needs to go.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
