I could do something like that which will of course end up resulting in
my creating helper methods that look suspiciously, exactly, like
private*Stream. The main argument I'm making is that accessing files
via streams (which get passed around *a lot*... typically only a bit of
top level code even knows or cares if it is a file) is a pretty common
use case so why not just acknowledge it and make them public in name
