I once modelled an Allied Alligator converted to be used as a radio controlled carrier for a one-ton mattress charge againt bunkers and walls on the Niormandy beachs, in 1/35th scale.50 years ago, Model Railroader commented that while some details were too small to be modelled in scale (I think they were talking brake wheels), they were too prominent to be left off.
Most scale rivets are probably less than the thickness of the layer of paint over them. They become noticeable with side lighting that creates shadows.
I sat beside one modeller who was putting bolt heads on a model by drilling a hole, inserting a length of plastic rod, and cutting it off above the surface. (This was O scale.)
