My understanding of the PPPoA/E deal is that SPs (originally) wanted to prevent some yahoo with a DSL modem from just being able to hook in to someone's existing DSL connection and using it, so they decided to implemement PPPoA and require some sort of authentication to prevent this scenario.
Also, DSL was the upgrade from dialup in many places, and dialup is generally PPP. For ISPs, the re-engineering required north of the last mile is much less, particularly in the billing/accounting systems that no one wants to touch because they were written by that coder who left a few years ago and work just fine. -- Nathan Ward
