JW411. I retired two and a half years ago after around 35 years in ATC, the last 31 years as a Heathrow controller. I probably am out of touch, as I often make clear in my postings. However, I DO check the latest version of various documents and I DO remember why some decisions are made.
I know that the majority of pilots say that they would fly the ILS GP, but enough didn't to warrant the change in procedure. Maybe you haven't seen what goes on underneath? I have seen enough to know that the procedure is fully justified. Even so, some pilots still bust their levels when being vectored for the ILS...
I am very sorry that you find UK attempts to improve safety to be sad. We may not be as slick as some... but we shift large amounts of traffic safely and comments from crews suggest that they like it.
