My current preference is to use only new-style generated scripts for the scripts field in the files section, and to let people use the data-files/resources system for old-style file scripts.

We’ll have to think about the shebang munging and decide if we keep it.  I think recommending that people use “/usr/bin/env python” (or python3) and not doing anything to the shebang may be the best thing.

This is also a bug in current distutils and distutils2 scripts.  Scripts should always be regenerated, as they depend on the running Python, not on other files.
