Status of placement=transition is "in use" not a proposal. I added the proposal in this discussion because it is more detailed and explains the history of why it was added. Placements are the only way we can know which part of the street segments are not aligned with the real lanes, and this is especially important for precise routing of vehicles. I add more precise information because some people need this information and will need it in the future. I understand that you would mlike to keep data as is, but we need to accept evolution of tags and new tags + new paradigms in OSM. These precise lanes and transition data will make it possible to simulate exact highway/motorway capacities, which was not feasible before. What do you want us to do exactly? Stop adding the placements? Revert them? I would really like to have a conversation with you about this, because I did not get any comments from other OSM contributors about this issue. Please contact me in a private message to schedule a videconference. I will explain in detail with examples why we do this and what we can do with it. Thanks and have a nice weekend!
