I know that you have given thought to the adoption of a model for the UK that reflects (or actually is) EFTA membership.
I was expecting the EU to be much more strategic thinking in their handling of Brexit and have worked on 2 approaches.
1. To get Brexit cancelled - this is the way that they went - understandably given all the signals they were receiving from the machinations at Westminster, but they do appear to have put their eggs in one basket so to speak.
2. Design a model as described in the article linked below. Although it would have to have been called something other than zone 2 of the EU - something like 'FTA for strategic partners' - and establish this with the UK. Following set up with the UK they could in parallel have designed their Target Model and planned their 2 or 3 speed Europe. They could then accelerate integration with a willing core and transition countries less committed to integration and counties such as Norway and Switzerland - or all EFTA - onto the same arrangements as the UK. This would have given them the opportunity to purge any quirks that have historically developed during the setting up of EFTA and the EEA.
Taking the 2nd approach would have resolved so many problems and have allowed countries to progress through what are essentially different levels of membership without being vulnerable to the emotive challenge of processes seen as joining / membership etc.
Really quite surprised that they have allowed the process to become so black and white for the UK - such was their confidence that Brexit would get binned I guess.
