[Tagging] proposing a page on the wiki: "tag names do not always correspond to their definitions"

[Nathan Edgars II]

I'd like to propose a page that basically says that just because a tag 
is named X, that does not mean that something should be tagged as such 
only if it meets the real-world definition of X. The following examples 
can be included:
*Many cities are tagged with place=town
*Bikes and pedestrians are allowed on many highway=motorways
*Many highway=trunks have been detrunked
*highway=motorway_junction is used for all classifications of road
