Ian,
That's a pretty good list, but, I'd disagree with you on containment mounds on a site specific basis.
Containment mounds almost become necessary where there's a need to buffer visual or acoustical problems.
ie, a fairway or green might have a favorable backdrop such as woods.
At the same time the course is being built, the woods are being cleared and a home, factory or commercial enterprise is being constructed on the sight lines behind the fairway/green.
A containment mound is the perfect buffer to shield the golfers view and/or quell the noise created by the newly erected object.
Trees are often inadequate because you can't plant mature oaks or other specimens that will produce an immediate curtain.
Containment mounds produce an instant effect.
In Florida, and perhaps elsewhere, you can't bury debris beneath the ground in certain jurisdictions. thus, covering that debris with dirt and crafting a containment mound can have a dual purpose. Getting rid of the debri and buffering visual and acoustical nuisances.
I would agree that containment mounds, for containment's sake, tend to be overdone and seem to detract from play.
Some are used to isolate the golfer on a hole by hole basis.
Some are well done, others not so good.
But, they can serve a valueable purpose and shouldn't be automatically dismissed.
