Engineering culture fetishizes engineering and tends to look down on implementation details. Why would you care about spec'ing a standard thread, that's the toolmaker's problem. Why would you care about leaving enough space around components to assemble the device, just outsource assembly to some 3rd world sweatshop full of kids with tiny fingers.

And then everyone wonders why new engineers spend their first few jobs trying to design crap that's hyper optimized for what it does but can't actually be built within any reasonable set of constraints.

CS isn't quite so bad but you definitely get some profs with that same optimization worshiping attitude.
