It takes two seconds to write `EVIL_IDS_THAT_STOLE_OUR_LUNCH_MONEY=[1] [...] NOT IN EVIL_IDS_THAT_STOLE_OUR_LUNCH_MONEY` instead of `NOT IN [1]` and then not hate your past self six months from now when you have to figure out why something has been excluded.
If some code can't be understood today, it's not going to be able to be understood when someone comes to modify it. Maybe in your domain all the code is write-once-read-never, but for those of us maintaining enterprise software that isn't an option.
We absolutely expect our reviewers to fully understand the code. If you want a quick shortcut to make that cultural change, have any bugs in code go to the code reviewer instead of the original author. You will find people start taking code reviews a whole lot more seriously.
