Not sure if you’re joking, but in a way this feels very true to me. After a decade or so of doing OOP, I started doing a lot of 6502 assembly (for a home brew computer) and not applying OOP principles felt dirty at first. Same as not having 100% (or any for that matter) test coverage. I felt like I was cheating by doing things a simpler way. But then I started to really enjoy it and it felt liberating.
