Do you mean `public_transport=platform` [^1], `railway=platform` [^2] or both?

If `railway=platform` means the same as `public_transport=platform`,
then the wiki page about `railway=platform` needs an update, because
it currently reads 'a railway platform'.

'Unknown' means we don't know anything. If `railway=platform` really
is identical to `public_transport=platform` this would mean that there
is no way to define that there is no platform.

Why not just 'stop'?

It's never too late to correct a mistake ...
