The repercussions of the certification authorities no longer abiding the reciprocal certification would be a big deal.
If EASA doesn't accept the FAA's certification do that make the reciprocity agreements null? So the FAA no longer accepts EASA certifications?
Not the sort of thing the OEMs want. Dealing with a dozen different authorities would severely delay things and greatly increase the costs.
