Maybe the stand-down Brexiteers on this forum can provide an answer.
From the FT today:
“Johnson said that all GB-made goods should be able to go into Northern Ireland without checks,” said one EU official.
Frost’s proposals are expected to include an “honesty box” approach, where companies that said their goods were destined only for sale and use in Northern Ireland should be exempted from checks on the Irish Sea border."
Britain also wants Brussels to agree to a dual-standards regime that would allow goods that conform to UK rules to circulate freely in Northern Ireland alongside EU-compliant products, so long as they were labelled as only for use in the region, according to people with knowledge of the proposals.
Another strand of the proposals is expected to seek to remove any role for the European Commission or the European Court of Justice in the operation of the Northern Ireland protocol.
The UK is also expected to argue the threshold to trigger the protocol’s Article 16 override mechanism has already been reached because of the impact on trade."
Liam, where are you?
