The thing that occurs to me is that one might want to write an administrative tool in Python to manipulate site.py, or even just some data that something in site.py would load. If exceptions from site.py were fatal, then bugs in such a tool would be completely unrecoverable; in trying to run it to un-do the buggy operation, it would crash immediately.

I don't think that modifying the site.py file is a good idea. Why not editing/generating the sitecustomize or usercustomize module?

Anyway, if you write such tool: use a different language or use a failsafe Python interpreter dedicated to this tool ;-)
