There's a misunderstanding, generated code is only "modified going forward" by very immature organizations. For extra negative credits there is the false idol of "round-trip engineering", like in the old Together Control Center, usually involving UML.

Generating from nice models and nice templates (the real source code) verbose and correct "boilerplate" that won't be usually read, let alone modified, is simply a shift to an ad hoc, specialized programming language.
