Why? Don't pollute the data like this.

This sounds like a job that is particularly well suited to be done 
during the processing of data needed when importing OSM data into the 
routing software database. Why you would want to leave it up to humans 
bound to make tagging mistakes or forget to add it is beyond me. I 
suppose editors could automatically add/remove the tag, but that just 
gets me back to my first point: why?
