If we update PEP 8 for our needs to say "Numerical literals should not have multiple underscores in a row or have a trailing underscore" then this is taken care of. We get a dead-simple rule for when underscores can be used, the implementation is simple, and we get to have more tasteful usage in the stdlib w/o forcing our tastes upon everyone or complicating the rules or implementation.
