My English was perhaps unclear. The discomfort is with using the same tag for two quite different road types (industrial estate roads and country lanes). Either would be fine on their own.
The potential problem for renderers is that there's a lot less space to render things in urban areas, so they benefit if lower-order roads are distinguishable between urban areas (so they can be narrowed or suppressed), and rural areas (so they can be used to help fill up the space). Abutters seems to offer one way of indicating to the renderer that it's within the urban area without creating yet another highway tag.
