Where is that wording from?

None of the RIRs guarantee any routability of any prefix at all.

They have programs like the debogon program which might mitigate these
effects but for the rest nada. RIRs also _can't_ guarantee this as it is
not their network to configure, that is the local policy of that ISP.
If some ISP decided to filter out >/16, then that is their policy.

Did you actually _look_ at the URL's I provided, also in text in the
email, showing that 86% of the networks are fine!? For the remained we
*know* which sites are wrong, fixing them up requires only that those
sites wake up. Nothing bad there.
