Thanks for posting this - I'm going to be using ryanair in a few weeks and wasn't aware of this new restriction.
I've got no problem with the carry on bag being put in the hold given it doesn't cost extra, but the main thing is knowing in advance to pack valuable items separately in a small bag which I'd rather have with me in the cabin.
