What gets me is
While the agreements involve some elements of continuity, they do not constitute a replication of the UK’s regulatory arrangements as part of the EASA/EU framework and many sections of the aviation and aerospace industries will face changes after 31 December, as this microsite sets out.
We will study the detail of the new agreements and will update relevant pages of the microsite as information becomes clearer about how the new arrangements will work in practice. We will notify stakeholders of the updates through the SkyWise alert system. If you haven’t already done so, please subscribe to the EU exit category in the SkyWise system:

So who was advising on the Government on the agreement? Because that reads as if the CAA had little Input into the workings of it.
