I think an EIR would be pretty useful..... UK airspace would "disappear" and so one could file from sunny Edinburgh to sunny L2k for lunch, and the flight wouldn't have to dogleg around airspace, or risk busting airspace. If it is cloudy en route, no problem, you are not banned from Class A airspace, you just keep going.
So you won't be able to fly the ILS at L2k...well, you can fly it down to 1000' cloud base I would imagine or find a hole, so it'd have to be pretty miserable and would suit most PPL's very well. It is a shame it doesn't include a precision approach capability though as I am sure many holes will be appearing in clouds which previously didn't have a hole
