Although I've never met Abigail, I'm pretty sure I speak for him (and most others) when I say we have not been similarly lucky. I remember nearly being fired when pointing out the deficiencies in a given design. (And, I'm sure it was part of the reason why one of my contracts was ended early.)
And, there's no reason why you have to follow the designs given, if they're stupid. If I was a programmer on that project, I would implement my own DAOs and write it that way. Then, when my one piece has good performance with the ability to choose which DAO to use in a given situation without impact ... results speak for themselves much louder than anything else ever can. (I've done this method, too.)
We are the carpenters and bricklayers of the Information Age.
Please remember that I'm crufty and crochety. All opinions are purely mine and all code is untested, unless otherwise specified.
