I'm always standing in the contributor point of view. It is not the
wiki (or better said "our recommendations") to follow the osm2pqsql
style file but the opposite. I was asking myself why I accept so
easily a 2nd tag for the highway closed loop and not for the railway
platform. And this is because my assumption is coming form my own
experience like all other mappers. Adding a 2nd tag is acceptable if
we all meet at least some substantial examples IRL. Adding a 2nd tag
just to fix a theoritical issue is much less acceptable, especially
when the main reaction is to say that mapnik/osm2pgsql will fail
because the assumption is done on a key, not a key/value pair.
Here we speak about a non-obvious assumption for the 0.0000000000001% cases ...
