It may be good in the book but I can understand why they've cut it. It's too slow an ending to the film, and basically amounts to quite a large scene with so many characters there and not doing anything except attending the funeral. What they will probably have instead is McGonagall speaking to the school as she becomes the new Head.
Personally I'm liking these bits of script. The thing with Ginny is definitely the right way to go. Their 'relationship' in the book is one of the only places where JKR went wrong (IMO). Of course, she could only do so much because in the end kiRAB are reading, but it was still dodgily handled by her.
