I think your ideas are very attractive, and those who think you are stupid are quite extreme with your ideas. In this forum everyone can say their dreams.
However, considering the practicality, it is completely impossible because for a large enterprise like Yamaha, all their ideas are money. Maybe they have come up with a lot of good things but they will not put them all into a Genos generation, but they must plan to release it one after another from Genos 1 to Genos 5 ... etc ...
From your idea, I have a new idea that Yamaha will sell features in patches, and people can go to Yamaha online store to buy patches, just like they are doing with the Premium package.
People can choose the features they like, to create a base firmware installation of their choice, of course Yamaha will need info Genos to manage their sold feature patches. For ease of understanding, you will buy feature patches and combine them and create a firmware installation file, the same way we create CPI, PPI files from multiple CPF, PPF packages.
With this way Yamaha will manage features and collect money from their ideas.
This is more feasible than programming applications like your idea shows.
