Yes, of course, I mean _good_ manual contribution, I thought this was

Well, this should not even be a problem as a bad import should not happen
first ;)

It looks to me like we're focusing too much on the past bad experience. We
must learn from them, not to do the same mistake twice but not consider
that because is went wrong it will also go wrong.
