Unfortunately the smartest minds in CS are exactly suggesting “don’t reinvent the wheel”. Maybe your comment is quite relevant for GitLab, because of their admirable publicity on their outages and code base, but I’m quite sure that even your TV has the same weird layers over layers that do something for the sake of “ease of developing”

I’m always surprised when I see a working complicated software, because I know that lots of projects, today are duck-taped patchwork.
