Hi

You *may* have a valid point there. Maybe the local tagging convention is different but before you start tagging ways in this way I would strongly advise you to seek out the local community (I don't know which channels they use. So check out community.openstreetmap.org or the wiki) and ask them about it.
IF there's a "vote" in favor of your way of tagging ways, go ahead. Until then I'd go with the wiki which clearly states the legal rules are tagged.

Sound good?

Cheers
