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.
