Picking up from #1328 it looks like we allow access=* and motor_vehicle =* at early zooms. We should either consider dropping access=no related features at low zooms, or at least drop access=yes properties from features at all (or just low) zooms to promote more feature merging to achieve smaller tile size and better label rendering.

access=* related tags we use now:

• access=*
• surface=*
• vehicle=*
• motor_vehicle=*
• bicycle=*
• foot:*
• horse=*
• ski=*
• snowmobile=* (we reference snowmobile=designated but don't seem to actually export the snowmobile tag now, a bug?
• snowshoe=*

network related:

• cycleway network at low and mid zooms (should mostly just be the boolean is_bicycle_related)
• bus networks (network, shields) at low and mid zooms (should just be is_bus_route)
