I'm away for a day and htere is suddenly huge walls of text that i have only been able to read diagonally... hurray for not being able to sleep and be awake at 3A.M.! Anyways, about the PDK it was bothering me too to lack the means to 'scaffold' a project on new or existing projects. It also was self contained and indeed you could have your own tooling to it. However, it was quite cumbersome to do customization on it
