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.
