Isn't the problem with GNSS approaches in the U.K. more the requirement for approach trained controllers?
No. The advent of CAP1122 in the UK provides for IFR approaches at locations without Approach control. However, as it stands, AFISOs are a prerequisite as Air/Ground only is (currently) unlikely to get approval according to said document.

Nice to see the focus on the
really important aspects of this safety related debate.....
