IMCR is not the same as IR Lite
There is one difference between the IMCR and anything based too heavily on a full ICAO IR (and this also covers the oft-touted FAA IR route too)...
The IR requires good colour vision and the IMCR does not.
It would be a shame if the Eurocrats decide to swap one for the other believing the training to be substantively the same (as if they'd actually care about that) only to discover that some Colour Vision Defective (CVD) pilots are suddenly excluded.
...but I have no doubt that's exactly what will happen.
