It makes sense, as telcos have pushed DSLAMs from COs to the curb over the last decade and are using distributed DSLAM architectures. Of course they have the obvious advantage of being all-IP already so video/DOCSIS RF combining isn't needed at the curb/node. As MSOs move to all-IP in the future and we are left with just DOCSIS those devices may get less complicated.
There are some downsides to distributed architectures and most PON/Active Ethernet (Google Fiber) deployments are not distributed. You potentially put more expensive devices in the field where fewer customers are served.
