If your question is whether it will be more work for Apple, the answer is yes, to some point. If you're also wondering whether Apple being mildly inconvenienced matters for the EU court or most users in general: honestly no. They're at fault in the first place, and if for a new feature that took 2 years to build, users have to wait some extra months because of that decision, so be it IMHO. That has always been happening with the US only launch features, and nobody's been crying a river.
