That's a contradiction of the PTv2 scheme: it says that
public_transport=platform is the waiting area, but also says that
highway=platform/railway=platform (which mean a physical object) is
equivalent to public_transport=platform.

How to tag the physical object (raised structure) in PTv2 then? And
how to tag extra platforms that are usually not operated, but only in
case of special events or diversions?

This is why i think we need two tags: one for the virtual object
"waiting area of a stop" and one for the physical object "platform"
(raised structure). In PTv1 we already have that, the only drawback is
that the logical object highway=bus_stop/railway=tram_stop cannot be
mapped on the same area as the physical object
highway=platform/railway=platform (as they use the same key).
Therefore my idea with a new public_transport=stop tag that can be
combined with highway=platform/railway=platform.

It should definitely not be mapped as railway=platform, as this tag
means a real platform, that is, a raised structure. Besides, it's not
possible to draw a verifiable waiting area in case there is no raised
or in any other way bordered area.
