Now, what I really want to see here is something similar, but for relations: being able to ask for a certain version of a relation from the history and seeing how it looked back then with its members also like they were at that time. If someone edits some roads nowadays and doesn't see that there are route relations on the roads you could end up easily with a situation where it's virtually impossible to know how the route was going, because ways were moved, merged, and deleted, and the list of way ids you get from the history is not helping a bit. The only option would then be to search for and contact the person who created that route there and hope that he's still active in OSM and still has his notes somewhere so he can retag that route. If not, then the only option to fix something is to resurvey, and that seems like a waist of time given that the information is in the database.
