I think you patch was too perfect. Always leave some small thing for the gatekeepers to latch on, then be all "oh, yes, totally overlooked this, thank you, I'll fix it ASAP".
What the hell is wrong with people?
In most corporate projects, odds are you're dealing with a much smaller pool of reviewers.
With a lot of people you will never need this. But especially in larger projects where any number of people might latch on and review submissions, the chances for someone to find something to complain about goes up rapidly.
And when one person has found something to complain about, all kinds of other social dysfunction quickly becomes an issue too.
