There was a change on the highway key wiki page, that interferes with the concept presented here.
http://wiki.openstreetmap.org/index.php?title=Key%3Ahighway&diff=317630&oldid=317451 User Dieterdreist has changed the description so the highway tag is no longer used for the objective physical description but for a subjective feeling of "importance". Millions of highway tags would need to be reviewed if this change without proposal and approval would become valid. Two important aspect of routing, the estimation of time to arrival and finding the fastest route, will fail if the highway tag does not stick to physical facts. Several other established or proposed tags like maxspeed defaults are negatively affected by changing the highway concept of tagging. New OSM contributors learn bad practice from the start when the first tag they learn is switched from hard facts so unsure estimation. Probably new users have already done large damage to the map by mapping or changing highway tags from the facts to the feeling schema, resulting in worse quality of calculated routes. IMHO this is a new dimension of vandalism. I don't think that this is done by concurring commercial map providers, but this subtile method of weakening the OSM tagging schema and therefor lowering the quality of OSM data would be a really cool attack against OSM, because it is not possible to search for and revert such changes systematically. I think that we, the community, should not accept such severe changes made to extremely used and highly established without the proposal + approval workflow. I ask you to support the reverting of the unapproved changes in the wiki and in the mailing lists. I also think we need a consensus that tag descriptions for tags that are used more than 100.000 times shall not be changed without a proposal.
