What most CMS products miss is; in real world, a company spends a lot of energy on not just building software, but also operating with the tools they build. I haven't heard any love story about people who write content. Developers build their stuff quicker, editorial teams look at a screen that look completely irrelevant to their work. People hate their jobs and may quite because of the horrible UX experience CMS products deliver.
This is my feedback. As a developer, I'm not looking for another Schema-to-GraphQL generator. There are too many of those. Good ones and shady ones. Nobody would miss anything if somebody decided not to build another CMS competing with the existing ones today with slight differences.
The bigger challenge is to build something not just developers, but non-technical teams love.
