I hate those kinds of abstractions, ends up becoming as useless as it is all-encompassing.

Take linux "everything is a file", yes, your word document and your sound device are files, also how do you increase the volume of your speakers, er.... it's a file and you can write to it!

The usefulness of a system lies in the stances it takes, it takes guts to be opinionated. It's easier to create a system of stem cells that can be anything and can be configured to your needs, all you need to do is write a turing complete configuration file.
