I think it's probably to make it more saleable, doesn't have octaves and no keys more remote than A/Eb major.

I was playing a while ago from an 'easy piano' book for sightreading, it was a transcription of part of the Tanhauser Overture and at one point modulated into Gb Major

I would have thought that they could have transposed it for an 'easy' version! Then again they'd probably have had to start in a horrible key to get that section in a nicer one (I probably would have just left that one out if I was publishing the book myself!).
I personally am looking forward to doing an exam without something on the syllabus that is from a collection called 'X easy pieces' or 'X pieces for children' I've not made it yet and don't think that I will be doing at grade 5 either!
