Are we reading the same thread?  For my last several replies I am very 
biased against bytes (and I know I'm not the only one).

Just not so biased that I'm unwilling to let clients say, "No, I'm 
really okay with getting bytes back".

I really like Koos' ideas because they allow the client to say:

- I only want str
- I only want bytes
- I'm okay with either

If the client says "I'm okay with either" then I fully expect the client 
to have code to properly handle str vs bytes after the fspath (or 
whatever it's called) call.
