[talk-au] Correct tagging of railway=platform where it is a sandwich platform

Thank you Andrew and Warin,
There are 1734 platform_edge elements, mainly in Germany and
surrounding countries as well as in London and 3 in South Korea. I see this
probably being a better solution for underground or complex interchanges
where platforms are not visible however I do think this is overkill and are
1700+ elements going to become standard in all the rendering engines as
The backstory is that most Melbourne stations with a sandwich platform have
been commented on that they need to be split and this appears to be a
rather tedious process that has little reward to very few. I want to make
sure that we are future proofing this and the best way to proceed.
