The laterals would be required for handrails, differing number of steps 
from side to side.

Adding tags on the ways does several things;
provides present routing on any connection to any outer way - including 
the laterals
present rendering of the out side area
stops validators and quality tools complaining about the ways.
shows the shape of the area. While most are rectangular some are not.

By making a system that maps all occurrences in the same way there are 
no edge cases that have to have specials.

The relation will still draw attention, but that is only one 
warning/error rather than 5.
