I think you misunderstand. Anyone can write code for rockbox, we just don't provide a way to install applications, instead you must add your code to rockbox itself, and then recompile the whole thing. This won't be changing, so no need to suggest it.
And in the future, please take a few minutes to read up on how things work before making assumptions. This forum is for discussing ideas, so its expected that you've put a tiny bit of effort into understanding what it is you're suggesting before you post it.
