The "form" here is a metaphor for "simple things". If i have a large system and I have 3 forms, I'm not going to add (or worse, build) a dynamic form generator system. Worse, the forms could be completely different or all have very special ways of working that can't easily be generalized. At that point its a lot easier to build them by hand. However, you don't need someone with a degree in software engineering to do that. Repeat that for any other "simple but easier to do one off than to engineer around" programming tasks. Not to different from factory automation. A lot of stuff done by hand COULD be done by robots. Its just cheaper to do it by hand.
