OK, to start beeing concrete, and because I got the idea that tagging according to importance is widely supported in the different countries, I edited the page. The result is here: http://wiki.openstreetmap.org/index.php?title=Key%3Ahighway&diff=316036&oldid=315699 In the first place, I changed physical to importance. Then I deleted the passus about implications to reduce data, because it's IMHO not the OSM-way to assume other tags instead of setting them, just to reduce data. Also there have never been definitions of those implications (besides perhaps surface=paved for upper highways). I added a paragraph that it is useful to addionally describe physical attributes like lanes, surface and width. Maybe more could be added here. The advantages for tagging according to physical state have partly become advantages for importance ;-) I added the paragraph, that before was titled "== Exceptions to physical attributes ==" also in advantages of importance ;-) so don't be shocked by seeing all red, it's partly due to the wiki that didn't understand that most parts are merely unchanged but just moved. Please comment, I see this as a proposal, and we can change it. Please don't forget, that this is the main definition. There are definitions for each highway-type that will deal with all the exceptions and particularities of the different types.
