We have this already, but for 4.2 - 4.5. No one has made a "CFW" for 9.2 yet, and it isn't likely anything like that will be released.
As for the Homebrew Launcher, due to the nature of how it works, it will never be in a format that can be installed to the menu. Ninjhax is very unique in how it executes code, and while someone can write a new Homebrew Launcher, it won't be the same.
Nothing is stopping us. Just not a lot of people have the knowledge to develop at this level -- those who do either don't see the benefit of it, or simply don't want to be bothered with it; it's very complicated.
