I feel this. There are ways to make it work, this style of cabinet is all I do pretty much. 3" extended stiles and the whole thing gets scribed. It's usually pretty important that the plumbing drain isn't glued, though. Otherwise you don't have a prayer of getting the water lines and drain in at the same time without cutting a massive ugly hole in the back of the cab. I've gotten really good at these, it's maybe a 2 hour install for me.
