Odd, this, as I can immediately think of the opposite use case: several marked
bus stops, but the buses stop at random positions over about 100m of road
depending on how many other buses are present. Individual buses serving the same
routes will stop in completely different places (sometimes two or more buses
serving the same route will be present at the stop).
Please stop referring to the current widespread practice of highway=bus_stop
mapped at the pole as 'old': in doing so you are instantly raising the hackles
of those who have spent time on the ground mapping, rather than writing
proposals on the wiki.
For all I know the various discussions and proposals may have some value, but I
find the initial tone off-putting, lacking respect and overly confrontational.
It is not a good route (;-)) to building consensus. By far and away the best
approach is to map a specific area, and show how it really adds value to the map
and to a range of data consumers (not just a pet public transport router). If it
really is better than what exists you'll get people using it: telling people
they're stupid, which is the basic tone of many messages to this list and
discussions on the wiki is less likely to be successful.

Think of a terminal bus station somewhere in the center of a city. Four bus
lines end here. One platform of 50m. The four lines stop always at the same
position (line 1 is first,..., line 4 is last). Only one pole for all buses.
Where do you place your tags? Or how do you tell where to wait for bus number 4?
At the pole that is 40m away from the stop position?
It is up to you to use a new schema, or not if you dislike.
I usually do not map already mapped routes/stations again, so I do not have to
drop an original node. But when I map a new station I map stop position AND

highway=platform is for buses/nonrail
railway=platform is for train/tam/rail
What should be used if there are buses and trams at the same station?
I do not plan to replace existing tags with highway/railway=public_transport,
but I will tag unmapped platforms with public_transport=platform. If so this can
be done with a bot.
highway=bus_stop is used different. Sometimes as stop position, more often as
The meaning of how highway=bus_stop should be used differ. It can not be
replaced easily with a new public_transport tag.
