I reviewed your recent changesets and there is still a lot of unnecessary information in the name key. Again, the name key is reserved for the actual name of the feature. Anything additional would be classified as mapping for the render and is highly discouraged. https://wiki.openstreetmap.org/wiki/Tagging_for_the_renderer

Sure, but these codes are not found on the name key for roads, so why should they be on the name key for hiking relations? For instance, name=New York State Thruway and ref=I 87.

OSM's objective is to map what is in the real world, not what we believe is the most appropriate naming convention to assist with understanding. Adding codes and descriptors to the name key is redundant, incorrect and in my opinion even more misleading. The WayMarked renderers are already very robust and will render the ref key over the route and only render the specified route type (hiking, cycling, etc). Is adding this information to the name key really going to assist in understanding what the route is actually named?
