Its a nonsense offered to appease the IMCR holders in the UK and badly thought out.
Our best bet is a PPL IR based on the same flight test as the existing IR with streamlined ground studies and grandfather rights which allow you to go for a pre test test to determine if you are up to flying a full test.
The same with the ground exams.
IMO that is what we should be directing our attention to not a FOB OFF IMCR look alike in name only.
