yes, this page is indeed dating back just to April 2008, what means,
there has already been 4 years of tagging before ;-)

Well, you can do this, but most routers will try not to use
residential roads if there is another way. This protects residential
areas from through-traffic and travellers from slowly traversable
residential areas, but both of these are IMHO not valid for industrial
areas, that's why your aussie-way might produce slightly worse routing
results (don't know, just an idea).
