The claim that "chararray" is not understood is not true. I know
about the code. It's not that difficult of a piece of code. It's
utility can be questioned, but it was and may still be an important
part of Numarray compatibilty.
I was asked a question that I didn't have time to answer properly (it
would have taken more than 5 minutes). That lack of answer does not
constitute "nobody knows about" the code. It's a great idea to add
to the docstring that the code was created for compatibility with
numarray. But, I'm not convinced by any of the given reasons to
remove the code from NumPy.
