A/T tailstrike
You are right, its anecdotal what many think is that at flare if IAS drops way below the App spd then the A/T could kick in, MCP SPD and an abrupt uncommanded increase in thrust result in a pitch up causing a tail strike.
But no data or else Boeing should warn us about the same, advantages are min spd reversion and alpha floor protection. So I find it an excellent tool though let the youngsters kick off both in order to get hands on experience.
