I can see a value in pedantry in a professional setting from a signaling point of view. It's a cheap way to tell people "Hey! I'm not like those other girls, I care about quality," without necessarily actually needing to do the hard work of building that quality in somewhere where the discerning public can actually see your work.

(This is not a claim that the original commenter doesn't do that work, of course, they probably do. Pedants are many things but usually not hypocrites. It's just a qualifier.)

You'd still probably rather work with that guy than with me, where my preferred approach is the opposite of penalty. I slap it all together and rush it out the door as fast as possible.
