So you admit your workflow does not reflect in any way or form the needs and processes of even a small to medium org, let alone half a dozen teams or more? That's not a great point of few for someone with opinions that strong on purity.
Your comment completely reaffirms my original comment way at the top in that these frameworks largely exists so that employers can avoid any kind of investment in their developers.
Then it is not complex enough to support the needs of large projects.
You admitted it yourself. You work with a small group of people in small projects, but you got huge opinions.
Building a bespoke framework, for nothing of value except because you want to, isn‘t investing in developers, it‘s creating a huge cost factor for no gain.
