The responsibility is on the submitter to be "responsible".  But there's a
limit to the certainty of correctness you can expect from the submitter.
 The integration process (including gatekeepers) needs to help out as well.
If:
- erroneous commits only cause lost work for the submitter and the
gatekeeper
- erroneous commits can be trivially rolled back
- testing is highly automated
then we can have a more productive and pleasant developer experience for
everyone.
