Does anyone have official info about Windows K2?

It's all over the internet but does anyone know if there's an official place where we can ask for/discuss about things that could/should be fixed/improved in Windows 11 by the K2 project?

I have a wish list of things that I would like to see fixed/improved such as searching of files in Windows File Explorer and a more lightweight Windows Store process/service as far as battery, memory and cpu usage is concerned. Are these going to be addressed by K2?

Oh, and why was it named "K2", anyway?

Thanks,
