I'd almost go so far as to say most providers are stupid.  "It
hasn't bitten yet, so it must be okay" is very common.

Ingress filtering of downstreams?  Spoof protection for routers?
Separate ethernet segments?  Ha.  Just how "centralized" should
public address space be?

And you can't do this with non-RFC1918 addresses?
