I think it makes sense to tag a no-longer-maintained hiking trail in a manner that will still be rendered, but will be rendered in a manner that distinguishes it from an actively-maintained trail.  Some portions of a trail may remain visible for centuries, such as a well-built stone retaining wall.  Other portions may become impassable within months, due to landslides or fast-growing vegetation. Having both maintained and non-maintained trails marked will reduce the odds of someone accidentally getting onto a non-maintained trail at a junction point, a mistake that can be life-threatening in severe weather.
