I've worked for a small company that does an old boring ERP. In C. The oldest files in the library date to the late '80s. The whole thing runs on a dime, is super fast, and a few developers could manage the needs of tens of clients. Implementing orders in REST was probably done in a couple of weeks of work. PDFs have been there since ever.
