You'll have to connect the dots for me here, I'm not seeing the
problem. The ISP's local network is not "the public Internet." They
can use RFC6598 and even RFC1918 at their leisure. If they choose to
place services on those addresses and you want to use them, you'll
have to exclude them from your local filtering and/or your own
internal use. For everybody else, they're bogons.

Is someone out there defaulting consumption of the bogon list who
shouldn't be? What leads you to the strong objection about 100.64/10's
inclusion?
