There is a massive amount of compromise in a UI. Adding features adds complexity. If you need that feature you have to accept the complexity that goes with it, and generally you are happy to. However if you don't need that complexity you don't want it. The average person uses 5% of the features of there word processor - but there is very little overlap between any two random users, and each wants the other 95% they don't use hidden (or perhaps 90% as there is another 5% they will need or think they will need) Gnome seems to be focusing on the 1% of features that are common to everyone, which means you can't get your 5%.
Note that I've always been a KDE user...
