Interesting Question, you get two problems around Europe one in the UK where you are cleared on the LLZ and then can't get a word in anywhere to call established, and either miss the GS or start the descent and hope. In the rest of Europe you are cleared for the ILS approach and they turn you in so close that the GS comes in before the LLZ and I get the distinct impression that after calling for further descent that they were expecting you to descnd to the platform altitude anyway, or they tell you to descend with the GS .
