And you might even be able to retain your sanity if you enforce any 
particular class to be either bRichPath or uRichPath. But if you do that, 
then that still leaves DirEntry out in the cold, likely converting to str in 
its __fspath__. Which leaves me in the camp that bRichPath falls under YAGNI, 
and RichPath should be str only.
