No, it's more like saying "Cars which can't operate off of freeways
won't work" because there are a lot of places freeways don't go.

I've got no opposition to issuing addresses based on some geotop. design,
simply because on the off chance it does provide useful aggregation, why
not. OTOH, I haven't seen anyone propose geotop allocation as a policy
in the ARIN region (hint to those pushing for it).
