> Windows has stopped to use CRLF files
No, there are some places where a text file must be CRLF.
To name a few:
- Notepad
- Visual Studio .sln files.

Actually, python 3.0 goes even further from "C": 
- Python mostly deals with text files
- text files will return (unicode) text data, decoded with a specified
encoding (by default: 7bit ascii)
Many unix programs will break anyway: if they want binary data, they
will have to open files in binary mode.
After that, they will run on Windows with no modification.
