My current preferred heuristic is just to add a new default filter to the list: once::DeprecationWarning:main

Special cases are not special enough to break the rules.

In other words, I'm -1 on this. Not only does it add complication and inconsistency (bound to catch people by surprise) to an already non-trivial set of default warning settings, but it doesn't even solve any problem that I'm aware of. The idea that main scripts should get special treatment here is entirely gratuitous.

Antoine.
