No.  Turning it on, I discovered why off is default. When it on, it sometimes does surprising things on IDLE.  For instance, print('x') is (usually) a builtin and can not be stepped into.  However, it calls sys.stdout.write('x'+'\n').  Under Idle, user process sys.stdout is PyShell.Pseudofile, so when source is checked, 'step' on a line with print opens the file and highlights lines in the write method.

Step should ask before opening a file, and/or a 'smart step' is needed.
