I won't dispute that line of thinking. In that case, maybe we should
do something like
for other countries)
and even, where we have the data,
boundary=lot or boundary=parcel or boundary=property
Regarding the first bit, I imagine some kind of standardization may
occur in the future to replace statistical_unit the way admin_level
replaced border_type. Regarding the second bit, why isn't this done
already? Still, I'm thinking both of these approaches merit creating
full-blown proposals on the Wiki.
There's a concern in my mind about what to do when a single way is
used as both an administrative and a statistical boundary, or some
other conflict with the boundary=* key. My guess would be,
administrative trumps postal trumps statistical trumps lot. Tagging
on multiple relations would make the data complete.
