In the case of Python, formatting is a core part of writing the code.  Apart from that, I don't see much need for this, what with Emacs editing mechanisms.

I looked at the sample you mentioned.  It's reasonable enough except for the bizarre way of formatting a long parenthesized condition in an if statement (near the start of FrameDecorator.py).  So while I can't see any reason to use this, it seems ok as a tool that others might use if they like to do so.

I would object to having this mandatory.
