Anyone who has been through the Airbus training school at Toulouse will be familiar with two standard answers from the instructors there. The first being,"It is automatic". The second being, "You are the captain, it is up to you".
The latter is applicable in this discussion. Performance calculations dictate that you do not need to apply extra thrust following an engine failure, BUT hey if you need it, TAKE IT, all the way to the firewall if necessary.
That's why you get paid the big bucks - to make decisions and take responsibility for them. Or at least you did in my day, has any thing changed???
