This would imply that you cannot filter the routing table at prefix
lengths less than /48.  What's worse, outage of an ISP routes traffic
to a now-unrelated ISP, which must discard traffic at its own cost.
Better get rid of the aggregates. 8-/

PSTN routing is completely different.  In Germany, routing is mostly
static AFAIK, and there is no expectation that you can reach all phone
numbers from every phone (and it doesn't work in some cases).
