Yeah, I'd honestly be OK with dropping highway=* values other than
bridleway, path, footway, cycleway and road entirely and moving the
hierarchical view to highway_level analogous to the admin-level.

Sadly the odds of this ever happening are pretty low as people's
appetite for fixing entrenched problems with tagging schemes is
essentially zero at this point; it wouldn't surprise me if that ends
up to be a contributing factor in the heat death of the project in a
couple decades.
