Is the BDFL (Guido van Rossum) intended behavior,

the point is that, if an import fails somehow, you are on your own,
if you know how to cleanup things you can do that explicitly

OTOH the interpreter does not try to illude you to have
properly cleaned up things, because there is no general notion
of what that means ...

the precise rationale is something also Guido continously forget
about.
