There are various technical excuses but the long and short of it is many Western Euro countries have allowed the Animal Rights activists to influence legislation and public perception of dogsport (which is quite big over there).
So the SV and FCI have been on a campaign to make IPO more palatable to the uneducated masses as well as appease the AR idiots and the legislators that are being pressured by them. Its a losing proposition but unfortunately they seem determined to continue on this path.
Lets not forget that the SV and FCI are ruled by the all mighty show dollars that have no vested interest in tests that put any kind of pressure or expectations on the dogs. Just go through the formalities and stamp the dog appropriate for breeding thank you very much.
I think ultimately bitework will be banned in many of those countries..
Such shy animals are in all circumstances an encumbrance to their owner, who must be ashamed of such a dog, and a disgrace to their race. Under no circumstances whatever must they be used for breeding, however noble and striking they may appear.
