I have to agree on that :) Just thought this is the best we can do if we want to reduce the number of GUCs to a minimum.
It looks like discussion KDE x GNOME.
GUC that has simply effect on behave without performance impact should not be problem - like log_lock_wait, log_min_duration and similar. I am sure so we would it.
The problematic GUC are a performance, planner, bgwriter, checkpoint related.
