What I do wonder about is what will happen with the NATS site when some UK pilot enters a really funny route, with the names of various villages. Some people do actually do that.
That's exactly what I do for domestic (Irish airspace only) flight plans. It was what I was thought to do, before I knew any better. One day I got a phone call from AIS asking where a particular town that I'd put on my flight plan was, and they changed it to the nearest IFR Waypoint. So I assumed that that is what they do with all such towns...change it to the nearest recognised waypoint or beacon.
However subsequent to that, I had a visit to Dublin ATC, and they showed me all the stuff that they could see on their radar screens, including my filed flight plan info, and that did indeed show all the town names that was included on the route, not just recognised waypoints.
