I would think it depends on what you're making. Many fruit (country) wines have an almost unavoidable haze that will require either a light filter or gentle fining if you wish them to look "brilliant" in the glass.
Kit wines, on the other hand, seldom if ever require any fining or filtration...they are balanced to enable most nasty stuff to fall out over time.
I never filter my wines from grapes, but I make only "big" reds and they stay in bulk aging for up to two years before going into a bottle, and then usually a year in the bottle after that.
