Not trivial but quite computable in my view.
Computable, yes, but writing the code is no task for beginners. Unless someone writes a standard utility to preprocess an OSM file to add total_tracks=*, this is not a feature one can just drop into their rendering workflow. So from a data user's perspective, it's best to already have the tag there. Apparently there are already mappers who add this information (we just need to guide them to not put it in the wrong tag) and I trust wetware over software for this task. On the other hand, if someone wants to run a bot that adds total_tracks=* where it does not yet exist, and results are subject to human review before upload back to OSM, I'd be fine with that.
