https://tools.ietf.org/html/rfc7908 already documents the problem with 
"route leaks". What you're asking for is as far as I can tell already 
documented there.

Perhaps not the *WHY* (as in operator error in configuring things 
correctly), but that's exactly what draft-ietf-grow-bgp-reject is about.
