There are different philosophies regarding software development. The project as it seems follows Chuck Moore's idea which says one must re-write more often (vs abstract away, patch over, extend above etc.), and be more focused on particular usages (vs betting on hypothetical future cases) to keep software unbloated, quick, and truly navigable by developers. Apparently, this approach is far from being popular (majority of devs probably doesn't even know such thing exists) because programmer's time has been very expensive for decades. So code quality, speed, and especially size became much lesser concern compared to time spent. But people do practice it as an art form in non-commercial projects, and to enhance their skills in optimization. Writing a whole OS with GUI, and apps in FASM apparently is one of such exercises.
