Seems to me we wrote a document some years ago about how to address this. 
If the upstream ISP isn't willing to filter at their edges, then write 
contract language that the client is required to filter such traffic in 
THEIR border routers. The typical customer with a few T-1 lines and some 
small routers could easily afford the CPU power in their routers to 
implement a few lines of ACL filtering.

This sure seems like a weak reason to scuttle an otherwise useful and 
desired capability.
