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

My idea was actually to replace the misnamed public_transport=platform
with public_transport=stop and to abandon highway=bus_stop and
railway=tram_stop as well as public_transport=stop_position. All in
all that's not more tags, but three less.

Besides, as there were only one element per stop (even if the stop is
a platform), public_transport=stop_area would only be necessary at
stations.

I agree, it remains a highway=platform even if it's not operated
anymore. But when it's operated, the platform actually represents a
bus stop.

The number in my example refers to the place where people wait for the
buses, for numbers 1–7 this is the platform and for number 8 it is the
place on the sidewalk. So, where should i put ref=1 ... ref=7
according to you? On highway=platform, on highway=bus_stop or on both?
And which one of them should i add to the route relation? It were a
lot easier if there were just one object.

I find that proposal to be inconsistent and unnecessarily complex.
Inconsistent because sometimes highway=bus_stop has to be mapped
beside the road and at other times on the road, and because sometimes
there is one highway=bus_stop for one stop and at other times there is
one highway=bus_stop for two stops. And unnecessarily complex because
it not only requires a stop_area, but also a stop_area_group. In
contrast, my suggestion would only require stop_area's at stations.
