If Johns took issue with the concept, he'd have had one of his pets debunk it. Instead, he's having a villain say it, which means that he's taking issue with the complaint.
He's also showing how Barry really wasn't all that boring. I wholeheartedly approve of the idea, but I do take exception to the retcons to Barry's backstory. DC is allegedly the more idealistic of the Big Two, so why can't they have a hero who isn't motivated by some tragedy?
