AA's normal procedure is to perform a rolling takeoff. i.e. do not hold the brakes. That is not to say that pilots are forbidden from holding the brakes. Many locations _require_ holding the brakes! i.e. SNA.
In the end, it remains Captain's Authority what _technique_ he will utilize.

Highly doubtful the engine spool up is to MAX power. Even at SNA we don't (normally can't) hold brakes at MAX power. We do spool them up quite a bit though.
