My reason for deploying minimal-any was not for direct reflection attacks, because RRL already deals with direct reflection attacks. I wanted to avoid sending truncated UDP responses to legit resolvers. When lots of legit recursive resolvers are being attacked with ANY queries for one of my zones, I don't want them to hammer my authoritative servers with TCP connections. So, minimal-any means they go away happy with a small answer, and everything stays on UDP. Eventually I expect legit resolvers to deploy cookies, and I still want to send them small answers to avoid TCP when an ANY attack happens.
