Thanks for the answer. I'm not too sure about the proposed fix though. The platform is still there and should show up on the map, however it is no longer used for public transport and should not be used by the public transport model.

Another example would be a railway platform used to load and unload goods. It seems to me it should have the tag railway=platform (what else otherwise ?) but not public_transport=plaform. Regardless of its history (lifecycle prefix) and of its access tag.
