Not a big deal and if someone just keeps wailing away on obviously out serves they'll just seem like a total tool - to all three other players on the court.
I agree. It is very common. I have only found people taking it personal in mixed when an unintentional return goes down the line at the female player.
Otherwise unless you hit it into another court, for the most part I don't feel like hitting it over has been a huge problem. As the code states I guess it depends on what is considered a obviously not in play.
