However, as Andrew w/UUnet pointed out some time ago, you end up providing
transit in this way.

If the goal is to only announce 195/8, any provider numbered in that block
that is dual-homed with this "deviant CIX" and some other provider suddenly
starts providing transit for the entire "deviant CIX".

I highly doubt that this is desirable.
