The skills taught and learnt for the IMC rating is invaluable. Whether or not this rating actually exists ON A LICENSE after 2014 shouldn't matter.
If it doesn't why not issue a completion certificate, just like aerobatics?
After all the IMCR was designed for one to return home after inadvertent IMC encounter.
It wasn't designed to be a 15-hour easy-to-get IR with 20% of the training, which is what EASA fundamentally cannot accept.
