I agree totally Ian, I think there is a policy change to make a wider appeal for the crossword and the paper in general - falling sales everywhere.
I have said before that I also think "regular" winners names are now excluded and am therefore using "other" names and addresses for entries and have won recently doing this!
I tried to see who runs Dan Word website as it seems to have a complete answer set as soon as the paper comes out and would not be surprised to learn that the paper fed the answers to this to support my first point.
