> This is still possible, it just doesn't have any effect on a version 1 client.

I'm not sure, as the client is required to "abandon the current connection attempt" ([section 6.2](https://quicwg.org/base-drafts/draft-ietf-quic-transport.html#rfc.section.6.2)) when receiving a Version Negotiation packet, even without consulting the payload of that packet.

Doesn't that prohibit the servers from sending VN packets against V1 packets, assuming that servers would prefer serving all the connections that it can accept?
