This isn’t best effort.

The DEFAULT is “receiver prerogative” and if a receiver has a key - or decides it won’t accept packets without authentication - it can override the default. It can also check later, rather than only upon receipt.

Most of the arguments you have offered so far against this misrepresent the *default* as the only choice or the choice a receiver who has a key would necessarily make and must be made at the time of receipt. That’s not what the current doc says at all.

So far, I’ve heard others concerned about wanting to be able to have UDP drop packets with AUTH that either fails or cannot be checked. But again, that’s not what we’re talking about.
