This assumes that the author of that code will go back and address any code review comments. OP seems focused on shipping fast, which is fine, but I would bet that this means that any review comments that don't find showstopper bugs don't get addressed - after all, why fix nuts in something that's shipped and not broken? That's a tax on productivity!
I think people forget what taxes actually do for us.
