It is a mandatory cooldown for the neo, even after a short taxi to the gate. None of those are limitations though, which has a specific definition, requiring strict observation and a logbook entry for exceedence. They ARE good operating practice, and you can be sure it'll be talking point if you bust them in training or during a check.
Perhaps you should actually read it to refresh your memory. You're correct, it's not at ALL vague.
"Operate engine at or near idle for 2 minutes prior to takeoff (5 minutes if the engine has been shut down for 2 hours or more)." [ 3.15.2 & 3.16.4 ]
What part of that do you interpret as an opinion? Seems pretty cut-and-dried SOP to me. You do whatever you choose though, you don't have to answer to me.
Not sure what you mean about OET and 3 minutes? 3.30.4 says "Operate the engine at or near idle thrust for 3 minutes prior to shutdown." Didn't see a 'should', 'might', 'may', or 'maybe' in there. Throw a 'will' in front of operate, and it reads the same.
