It just signifies that someone has worked with enough pedantic developers that they had to form an opinion on something as insignificant as this, or that this person is pedantic enough to have a strong opinion on it.

I wouldn't consider the first to be a good indicator of someone's skill as a developer, and the second would be a good indicator that it was someone I didn't want to work with, but I'm guessing that's not how you're using it...
