My understanding is this was mostly legacy from devices that did not carry full Rib and fib. There were tricks to avoid ending up on these skinny devices if you wanted. Life in the core has changed a lot in recent years from 6500/7600 and foundry/brocade class devices to a more interesting set in the pipeline or released. There are some limited rib-> fib download boxes that could slice traffic in cost effective ways that the price conscious consumer will likely push the market to.
There are also of course variations on this. An an aggregation router may have quite limited FIB, e.g. enough for customer routes yet still have a full rib in it's control-plane, at which point it needs to default towards devices which do have a FIB in place. assuming a single hob peering it would be rather hard to identify this case as a customer, though if your neighbor has an Arista mac address for example that might be a logical conclusion.

I was told that it was now a special request and they would "try" to get it done and these days all their routers had full table capacity and they no longer used the multi-hop.
