[Tagging] Was public_transport=platform intended to always be combined with highway=bus_stop?

Hi

This is not a criticism of Joseph.

This post confirms what I've been saying for the past year - PT tags add 
nothing but confusion to OSM, which directly leads to errors.

highway=bus_stop is a completely separate tag to any in the PT schema. 
It was created long before the invention of the PT schema and is the 
original & the most popular, accurate way to map a bus stop.

The PT schema purely duplicates existing, well used, clearly defined 
tags. It adds no extra detail or information.

A platform is a raised physical object compared to the surrounding area 
to aid vehicle boarding. Popular tags such as railway=platform, 
tram=platform are used for such entities.
Public_transport=platform has been hijacked by PT to falsely represent a 
bus stop as an imaginary area on a pavement. As defined in OSM's welcome 
page: "OpenStreetMap is a place for mapping things that are both /real 
and current/ ".

It's hard to ascertain precisely why PT was originally created but it 
appears to be that the existing tags weren't complete. However instead 
of adding that missing data, somebody though it would be a great idea to 
start from the very beginning with a completely new set of tags & try to 
paper over the gaps. The irony is that, after a lot of discussion over 
tag names & locations & quickly waning enthusiasm for adding them to the 
database,  PT is *less* complete than the original data. What a waste of 
time. It's a mess.

Over on the transit forum the PT schema has become so convoluted even 
those who helped create it are baffled. At least one is advocating its 
removal.

It's time for the PT schema to be redacted.
